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 have sent you an email requesting additional information so that our customer care team can look into this further. If you could please respond to that email, our team will follow up with you. We appreciate your feedback. Thank you.
