I need to be contacted by executive customer relations

An xfinity agent somehow closed my mobile account when transferring my service to a new address. Now, I am unable to pay my bill (for data and my phone), access my mobile account and my service has been stopped until it is paid (i can't pay it!). I am still getting emails saying my balance is overdue and still had service untik today. I need this resolved asap, over the phone agents could not access my account and would only be able to give me an entirely new account.
