Smartwatch Nightmare

Help!  I am caught in a nightmare billing situation because I returned a smartwatch via FEDX.  Now there is an outage reported at my address.  There is no outage here and I cannot connect to agent.  System says agent not available due to outage.  I have talked to so many people including AI which I might add had the best answers.   My phone was cut off for four days because Xfinity claimed I had an outstanding balance which I don't.  Also the xfinity recorded said that I could lose my phone number.   I am wondering if the alleged outage at my specific address is related to my Xfinity Mobile nightmare.   I was unable to get through to a live agent.   My phone is working now but I wonder for how long.
