I made the switch to Constellation
I signed up for service on Jun 3rd. I believe the switch was made on Jun 6th. I received notice from ERCOT that my service provider had changed to Constellation, but I have not received welcome package or any instructions for setting up my online account.

We appreciate your feedback. Thank you.
