I am sticking with Constellation
I switched to Constellation one year ago. I have nothing but rave reviews for them. My bills are the lowest they have ever been in 18 years. I am sticking with Constellation.

I love Constellation. I had only been a Reliant customer. No more! My monthly charges are less than half of what I was paying. Will renew with Constellation and never go back.

Great Company! Great Service!
One of the best providers I have used. Hopefully when it is renewal time, they will offer the same plan if not better.
