Satisfied customer
(4.8 / 5)
“
Constellation communicates with their customers each month and gives them a comparison of the amounts of electricity used from month to month. They also give suggestions on how to cut power costs in your home. I have been more than satisfied with their service. They also began reminding me several months ago that my contract with them is about to expire and offered options to stay with them or find another provider. ”
