Constellation review

Switched over to Constellation mainly because price was better. Everything went very smooth.

Electric Bill Still Higher Than Expected

While I am glad to have received a better rate with Constellation, for a fixed 6-month period, no less, I will continue to search for a lower rate because my bill is still considerably higher than I had hoped, despite having gotten new weather stripping and additional insulation added to multiple areas of my house in the past few months.

Hard for me to review my experience with Constellation

We got off on the wrong foot. After I sign up for Constellation, my account was lost and never started, so when I called to check on what was going on, they said they were sorry but for some reason, I would have to re-apply, which I did and had to wait another two months before my service would start. Now sometime in May, 2026 I hopefully will be with Constellation and will be able to give a true rating on my experience.

Worst company to deal with

I found out today that I am locked into a 5 year contract with this company!! Would NEVER have signed with this company had I been told that up front. Was charged $2,000 for an early cancellation fee! Extortion! Just my opinion , but buyer beware!!!
