      I had no idea I was paying way too high rates on my electricity. All I knew was my monthly cost averages $500. I signed up with Constellation and I'm now paying only around 320 monthly. Although I signed up my gas to get an even better rate I am very happy with my decision.

      I feel lucky to have welcomed these guys in my store. I now save approximately $90 every month! My initial rate was around 15 and now it's around 10. I really don't know what to say here really, just came to show some appreciation.

      I am so excited for the fact that Constellation Energy is helping people save money with their fixed protection plan. Thanks, I was able to get insulation and a new heating system. They have excellent programs and I appreciate them helping the way they did.

      They get 2 stars for my initial rate when I signed up, but now they took away the offer that they gave me to renew, but when I originally called about it the customer service rep didn't know what I was talking about even though I received a notice for it. I could also go online and see the offers. So attempting to renew that plan today, they no longer offer it and want to double my bill. I also can no longer see the offers. Gave me zero incentive to stay. Offered me the same plans they offer everyone else.

      I spoke to 3 people over the phone and on the chat everyone gave me different contract end dates. All gave me different plans (which all doubled current pricing). Then everyone keeps telling me what my rate is but yet I'm on a tiered plan, I have to correct everyone because they do not look into my account before offering anything. It's extremely frustrating to have to now search for a new provider since they no longer are offering me a plan that is comparable to me current.

      BEWARE! Do not under ANY circumstances provide a Constellation door to door salesperson with your bill! No matter what they promise. Do not give it to them! So, this my story: I had a Constellation salesperson come to my door and offered to switch my electric supply for a discount. He asked if he could see my bill to compare, and because I am too nice and stupid, I was willing to hear him out. Well, after all was said and done, I said "No thank you." and he left.

      Well, jump forward several months later, and I receive a notice from Ameren saying my Electric Supplier Choice was changing at my request. I called Ameren, and was told that even if I refused their offer, nor signed any agreement, Constellation could switch me, because all they needed is my account number! And by providing them with my bill to compare, they were able to get my account number. It's pretty crazy, in this day and age of ID theft, that not even a contract or any identifying information can be used to make a major account change. But, the helpful person at Ameren told me this was the way it was. Constellation appears to be an absolute scam of a company, employing dishonest people. And if I ever see one of them come to my door, I am going to tell them to get off my property.

      Now, the reason why they waited so long to submit my supplier change is that they were probably hoping I wouldn't pay any attention, or not understand what the notice I received was. The very nice lady at Ameren let me switch back to Ameren as my supply choice on the phone, and all is well now. Again, do not under any circumstances give Constellation, or ANY door to door salesperson your electric bill. They will take your account number, and can at ANY time switch you.

      I switched over to Constellation from Reliant on a 6 month contract. The kw/h rate was lower, however, there a fee structure hidden in the fact sheets that I did not notice even I looked several times. My fault and I take accountability for that but I wanted to share after my recent experience. My monthly bill actually rose from the switch by a few dollars. I had 7 months left in my Apartment and I signed a 6 month contract. Without notice of my contract expiring or rates changing, Constellation electric issued me a bill that had more than doubled from the previous month even though I had used virtually the same energy as in the previous billing cycle.

      Constellation has no phone support and only offers 'Live Chat'. The website is utilitarian and it is not user-friendly. The live chat rep, Wendy, informed me that a notice was sent approx 1.5 months before contract expiration, although, there is no record of this in either of my email accounts. I was offered no assistance and Constellation's stance was basically 'pay it or else.' Avoid friends!

      Not worth your time. Did not set up my electric account. Still got charged when I switched to a company who could handle the account properly. A real joke of an experience. Stick with the traditional providers for this and you will be better off.

      2 guys were just at the door. On their bright blue shirts it said "Constellation". He presented himself as representing Comed and Nicor. Had a sample bill with some parts highlighted in green and stated that if I have 3 particular lines under the supply part then I am paying too much. Then he whipped out a Comed notification that he said I should have gotten but no one seems to notice on the bottom of my bill or online as a PDF. I said "I never got it". Then he would I take a look online now to see if I had these 3 lines. I said "no, I will check later". He said I could not do it and it had to be now while he was here (very pushy and annoying). Then I said "but it does not say Comed on your shirt" and he mumbled something obscure. What a scam.

      First, they increased my cost per kWh without notification. I signed up for 7.8c per kWh, then magically it changed to 12.8c per kWh. Obviously, I started looking to change providers. I bought solar panels and switched to a green company on March 26th. They called me on May 22nd stating I owed them $400 and that I was delinquent for Feb, Mar, and Apr. They also tried to charge me for the "minimum usage fee" in April (I canceled them on March 26th). I had auto pay set up, so how was I delinquent on a bill? "Oh we performed a system upgrade and it dropped people". I guess they thought it was a good idea to wait 3 months to tell me? They also never sent me the bills until I asked on May 22nd. And I thought I got away from these criminals. Stay away at all costs. Shady company run by crooks.

      They came to my store and fooled into switching my electric & gas service. They are dishonest and untrustworthy and a bad company that prey on the unsuspected. If you fall on their trap and later decide to cancel the contract before it starts, they will hit you an early termination fee of over $1,600. So beware.
