    Like many, have notified Constellation by phone and writing but somehow I keep getting navigated back as a customer. There are countless others and am discussing with two legal firms regarding a class action legal suit against them and maybe our local city as well.

    Company is a scam. They constantly calls and stops in my business and harass you to sign up with them. They sent me a bill for "early termination" and the letter that was sent with it says my contract expired 4 months ago.. Makes no sense!

      Unbelievably deceitful company. My last month bill was more than double what I pay for and it was in the middle of winter. That kept saying I went to variable the last month. Why was not this company filed a class action lawsuit and put the CEP behind bars.

      Constellation has a very poor cancellation policy. Fees are extremely too high. I will never deal with them again. A charge of $150.00 was added to cancel my service. I guess they don't wish to please customers.

      I called to renew my contract. I found out that they have been charging me 19.99 for AC and Heater insurance for 2 years. That is almost $480 USD. I am not certain if my contract is already in effect as I just called today and agreed verbally but if I can I will cancel that contract and find a new provider. There is no way I would ever have agree or will ever agree to insurance on principle alone. I do not support legalized gambling.

      This company is very deceitful. We had them for a couple years. Suddenly our electric bills skyrocketed over $1,000. As we had added a pool and sprinkler system we thought it was related. Finally, after two months of this I called Constellation and found out they had raised our electric rate to 24 cents a kwh without telling us or warning. After lengthy negotiations to keep them, they gave us a small credit. Recommendation, no matter who you have, if under contract, write a note to yourself in your calendar to cancel or change the contract when it is done. Don't rely on a group like this to do it. They will scam you.

      Truly scammed. I was interested in its Ad and got $50 gift card. Since then, my bill was charged almost double. Every month I received both bill from Eversource and Constellation! I cancelled it immediately, but still paid current monthly payment! No free lunch. This is absolutely a joke.

      How does an electric bill at 28 cents per kWh go down to 14 cents per kWh (town contract), yet my bill doubled instead of being cut in half at half the rate? Then I fire Constellation a week before I billed & now only using my main provider (National Grid) at 18 cents per kWh, and my current bill is now $63.00 cheaper than it's been with Constellation. It hasn't even been a full billing cycle, I'm paying 4 cents more per kWh with National Grid and I've been using more energy the past month, as my mini splits have been running ice cold full time 24 hours a day, but my bill is now down $63.00?! Make that make sense! Constellation is scamming customers! I see the same 1 star complaints across the board with previous customers and how their bills doubled. They need to be investigated for fraud!

      Somehow managed to switch my energy supplier to them without my permission. When I found out, I switched back to my old supplier. Yesterday, Anthony ** stopped in my business under the guise of being a third party company, Public Utility Services, that was hired by PSE&G to audit electric bills, specifically of customers who had complained in the past. I asked him if he was from a company trying to get me to switch suppliers and he said no. I told him to come back tomorrow and we'd discuss the bills. I then googled this man and found his LinkedIn profile in which he names himself as a regional sales manager at Constellation. Sneaky, slimy, no good sales tactics. Not to mention switching my supplier without my permission. Stay far far far far away from Constellation.

      Absolutely one of the worst companies I have dealt with in 30+ years. Bait-and-switch pricing, currently $150 more a month than our regular supplier, and a lying salesperson who assured me if I was not happy, it would be free to switch. Of course, when I tried to do that, they told me that I had over a year to go and would have to pay $3,000 to leave. STAY AWAY!
