Gets you in at a cheap price less than 2 weeks later an email saying the prices are going up more than I was paying before the switch

What incompetence! Joined with the assurance that rates have already gone up. Within three weeks received an email stating new rate hike above every competitor. Then sent a "no reply" email stating it was wrong. Who is managing this company because they should be gone! Customers leaving in droves. Don't go near this mob because they don't know what customer relations mean!

Less than 2 weeks after signing up with Sumo they increased their rates 22c per day supply charge and 9c/kWh, a 30% increase. Absolutely pathetic. I will be moving on after this dreadful brief stint.

From 1 August 2025, your electricity rates are increasing. It doubled my rate, trash.

Witin 2 weeks received notice that I was being moved to another plan and my delivery charges were doubling, usage charges up by 20%. Yeah right, how dumb do they think we are, I had a thought when I moved that this would happen and here we go. Online portal sucks, can't track usage and you cannot even see what plan you're on and what the rates are. This must be on purpose so you can get overcharged sneakily by this scummy retailer. Edit, was NEVER INFORMED as who would go through the effort of changing and then changing back. Silly obvious deflection from pathetic company

Terrible customer service!!
I called the hotline as I’m interested in joining the energy plan, but I have questions about my meter tariff. The staff is not helpful and rude, as the guy just hung up suddenly without saying anything or a polite ending that a customer service reps would usually do. Perhaps I couldn’t continue to sign up, so he just doesn’t bother to say anything.

I signed up and a couple of days after I was connected I got an email letting me know they were adding a extra 20% to the rates so I called and asked for the rates I signed up for and was given a flat out no.

I joined Sumo on the 3rd July after shopping around previously with Alinta. During the sign up process with Sumo, I was not advised of the rate increase was on the way, then I receive an email on the 15th July saying rates are increasing on 1st August, up approximately 30%. What a scam, I should have stayed with Alinta. I will be shopping around again after this debacle. Very disappointing outcome

I connected with sumo in July and 15 days later they changed the plan i was on to an ultra-higher one. I was with them for less than a month. Very annoying that the rates they offer on the website are not what you'll be charged. Almost feels like a scam to collect and sell your contact information. Would definitely not recommend. Date connected with Sumo: July 3, Date rates and plan changed: July 15 with start date of August 1st.

On 16 June we transferred to
Sumo and on15 July we received a notice from them that they were increasing the 4 categories of pricing by an average 35%…,disgusting; and it’s easy to change supplier; which I’m doing now

NEVER AGAIN!!! I had Sumo on my website and discovered an issue with an automated email that was hassling my customers. I contacted customer service. Their reply was to REMOVE MY WEBSITE POPUP! And then ASK FOR MONEY!!! They said it was part of an upgrade, I said fine, just remove it. No dice! I have reluctantly paid them, just to get rid of this email as I'm in the middle of a product launch, and can't make website changes (I've activated a free plan and cancelled immediately - fingers crossed. If I do get charged I'll post it everywhere)

Ever since signing up with Sumo as my internet provider I have had nothing but problems. I'm always getting "can not connect to this network" when I try to connect to my wifi. I have to reset my router at least 2-3 times a week and then I have to restart all of my devices to be able to connect. Yes I have tried to contact Sumo regarding this issues with no satisfactory result. Sumo is my electricity and gas provider. I will be find a new provider for all of these services in the coming week or two.

I have been with sumo for a couple of years . Like many I have had financial difficulties ans sumo has been the most understanding helpful and friendly service I have ever dealt with . I was so far behind and they still didn't disconect and happy to work out a plan . They also guided me to a service that helped with a 1 off payment to help me get back on track . Thank you to all the staff at Sumo . I would have been in the dark with anyone else

First - increase in energy charges in Jan 2025 that seem extortionate. Second - after cancelling my account and finding I had $200+ in credit - I realise there's been no contact re: refund. So I call (30mins on hold) and am told I have to apply for a refund - it's not automatic. OK - I give all details of account, name, and confirm the card details the operator reads to me as the one for the refund. Everything checked by the operator.

Third - SMS today saying they can't process the refund as they have insufficient or wrong information. Another 30mins waiting to speak to an operator (both of whom have been polite and personable, although there was no apology from the second one for the earlier error) to give details again.

Seriously poor customer service.

This is a dishonest company who just increased there electrical charges by over 30%on the 1Feb have left them and won't be back!!!!!

Just sent me a warning of a 32.5% PRICE HIKE.
In a time when we are all doing it tough it's hard to swallow such a large price gouge.
Whats worse The email I sent complaining to see if what I received was an error was
replied to refusing to help demanding I phone them up. I have phoned them a number of times
and spent over an hour on hold pushing various buttons including having a robot offering to call
Me back, but as yet not a single real person from SUMO has made contact.
It would appear Customers don't matter to this Mob regardless of their Fake claims.

Be careful. This company scams its customers. We signed up for a gas contract in late November. They repeatedly sent out someone to read the gas meter values. Both the person reading the values and Sumo's customer service on the phone assured us that the values have been read. The customer service also assured us that we could already use the gas with the prices stated in the contract before it is displayed in our Sumo online account. Weeks later Sumo canceled the contract and refuses to let us pay the already used gas under the contractual prices. We are now stuck with a much too expensive gas bill with the default provider. Sumo refuses to cover the damages and refuses to honor the legally binding commitment the made in the phone call which they recorded.

The young lady was pleasant & efficient & a pleasure to talk to.

I signed up based on the pricing and feed in tariff listed on their website plans.
Once I signed up the contract they send had higher prices and a limit on the size of inverter you can have to get a solar feed in tariff, this is NOT listed on their website.
Unless you read the fine print on the contract they send you, you will be getting ripped off.
An absolute disgrace!

Dear Sumo Energy Customer Service Team,

I am writing to express my deep dissatisfaction with Sumo’s current policies regarding rate adjustments for existing customers, which I encountered firsthand during a recent experience with your customer service.

It is extremely frustrating and disappointing to learn that when Sumo lowers rates for existing customers, customers are required to call and confirm the change to benefit from the reduced rate. If a customer does not call, the rate remains unchanged. This is not only inconvenient but also illogical. Conversely, when Sumo decides to raise rates, these increases are implemented automatically, without requiring any approval or input from the customer. This inconsistency in policy reveals a lack of customer focus and fairness.

When I called to discuss this issue with a Sumo representative, I was informed that “this is the policy.” However, simply stating that it is a policy does not justify its sensibility. This approach comes across as a tactic to keep customers on higher rates unless they proactively inquire, rather than transparently applying the best rates. This is far from being customer-centric; rather, it feels as though Sumo prioritizes company profit over customer satisfaction and transparency.

Additionally, I have realized that my current rate is significantly higher than Sumo’s standard rate, and I am uncertain how long I have been charged at this higher rate. This lack of transparency and customer focus has left me completely disappointed in Sumo’s practices and approach to customer service.

I hope that Sumo takes this feedback seriously and reevaluates its policy. A truly customer-focused company should automatically apply lower rates to existing customers, just as it does with rate increases. Failing to do so only creates frustration, distrust, and the impression that Sumo is not committed to fair customer service.

Thank you for addressing this complaint, and I look forward to your response on how Sumo will ensure fairer treatment of existing customers moving forward.
