"Representative was simply superb! And what a huge difference in comparison to some of the reps we have to speak with at ConEd. You blow them away!"

"Billing is my only complaint. Hoping it gets better. Everything else is wonderful."

"Horrible, worst company ever. Telling everybody I know about this experience."

"Customer Service was good."

"I went with Constellation thinking that it would save money on my bills, it did not. My most recent gas bill was about 9 cents per therm more than if I went with Nicor directly. If I was supposed to review my account every x amount of months to keep getting the best rate, that's my fault. It also was not told that I'd have to do anything but sit back and enjoy the savings? My bill should always be lower than if I went to Nicor direct using Constellation. I would guess that you buy a block of therms from gas company and get a discount for buying in bulk, passing on the savings to customer, then keeping whatever's left for profit. If this was really protecting us from rate increases, I think it would be better sold as an insurance policy, not a savings tool. Also, it would be appreciated if you return the $50 cancellation fee to me. I don't expect it, but it'd be nice."

"My experience was excellent"

"My renewal rate is higher than other providers and Constellation at this time. Representative could not lower rate due to length of contract. I will not choose a provider with a cancellation fee again."

"I should be able to call texas office directly from online search , i wish yal shared more tips to save energy, energy challenger to save money on the bill"

"The representatives I talked to were all very helpful and considerate. The last representative was going to transfer me to the department who could assist but, after being on hold for a bit, the department instead had him tell me to wait for an email response from them that I should receive in a couple of days."

"My experience with Constellation was good. The lady waited until I finished with my concern before speaking. She was pleasant and knew what I was going to ask. I'm very thankful she listened to my concern than talking over me with her answer."

"Not good I will call again yo see what is going on or what happen"

"I have not had any issues with Constellation."

"Would have stayed with you if you would have matched price."

"Very professional, pleasant, and knowledgeable customer service rep. Thanks!"

"Awesome, Thank You so much..."
