Response from Constellation· Jul 23, 2025
Hi Bob, We're sorry to hear that the plan you wanted did not appear for you. Our rates and plans do change based on a number of factors including demand, weather and more. If you signed up for a plan, you do have 3 days to cancel your contract in Texas and up to 90 days in other states. If it is beyond that time period, you may be required to pay an early termination fee based on the state you live in. We have sent you an email requesting more information. If you could please respond to that, we will have our customer care managers look into this for you. Thank you.
