Happy with Constellation so far

(5 / 5)

“  Left champion after 3 years when my contract expired and they jumped my price from about 7 or 8 kwh to 15 and my bill went up $200 for that month. They would not adjust at all so I dropped them. Constellation took over in November and the weather cooled off but the bill has sure gone down. ”

“  I had been with my company for over 15 years and when I got a bill for over 450.00 and they would not do anything to help, I started shopping. I have had 2 bills so far and the pricing has been amazing. So yes so far I am very happy and will recommend this company to everyone who asks. ”
