Have you received multiple opt-out letters?
If you are the account owner for several electricity accounts you will receive an opt-out letter for each account. The letter will not contain any account specific information due to privacy concerns. This makes it impossible to know which letter is for which account. In this scenario it is recommended that you contact the supplier, Constellation, directly at 855-310-5567. You can specify which accounts you want enrolled or those you want to opt-out.
