Price is a little higher than I want, but the length of the service was what made me switch back to Constellation.

2 month before you process my request in that time I switch companies for a lower rate. You then proceeded to continue with my application that you were late in processing and now charging a must higher rate. Very deceptive practice.

Hello, We are sorry to hear about your experience. Unless we received a request from you or your current supplier to cancel your switch request, your initial switch request with us would proceed as normal. It typically takes 1-2 billing cycles in Connecticut to change from your current supplier to a new one because the utility must approve the switch request. We have sent you an email requesting additional information so we can escalate it to our Care managers to look into further. If you could please respond to that message with the requested information, we would appreciate it. Thank you.

Billing error
I signed up for Constellation even though the rate was higher than my utility company’s rate because they offered a $75 gift card. When my welcome email did not reference the gift card I sent an email to confirm I would be receiving it. The email I received in response indicated I would not in fact receive the card and that my enrollment was canceled. I just received my electric bill and was billed by Constellation for the higher rate.
