Bad customer service & can’t get help

What a mess!?!? On November 14, I ordered Xfinity cable and internet at my home. I picked up the equipment the next day at your store on 355 North Federal Highway in Boca Raton. I paid $50 and had a balance of $85 to be paid on December 8th. I showed my driver license when picking up the equipment. On Thursday November 18, you cancelled all my service saying that the household had a balance. I called and was on the phone with your customer service agents. They said that it was my mother balance and she died on November 26, 2020 on thanksgiving day. Her cable was on vacation at time of her death and I even returned her equipment to a Maryland location. She had no assets. So, I’m at a loss in what world is it ok to link my dead mom’s account to mine. When I was on the phone with your company, I even gave my ssn number. I thought this was resolved as the customer service department said that they would close out the account and open a new one. They said it would no longer be linked to mine. Today, I find that I now have a $264 balance and no cable Or internet still. Your company is even calling me to return the equipment!!! This is wrong on so many levels. I called again this morning and your team hung up on me after another 1 hour wait. Then, I spoke to your chat agent group who said I needed to Fix my account by bringing my license in again because they didn’t believe it was me. I’m not really sure what is going on but this is wrong. All I was trying to do was get cable and internet at my house and I’m being punished.
