I fell down the stairs after trying to chat with Xfinity agents and now my bill is saying past due despite proof that I paid it.

I contacted Xfinity after I thought I accidentally paid my bill with a card that did not have enough funds on it. What I was supposed to do was split the payment between mine and my husbands debit cards but it did not give me an option to "pay another amount" like it usually does.

After I found out that there was no payment made, the person I spoke to decided they would try to get me "a better deal" based off of my usage. This of course was all a guise to try to talk me into getting Xfinity mobile. I know this because I just went through a long ordeal where I had to get the Better Business Bureau to assist me with fixing my account after several Xfinity agents completely wrecked it because they were focused on selling me Xfinity mobile.

Further evidence? After I said I did not want a mobile line but that I would like the agent to explain the difference between my current plan and the one they were offering just so I understood it fully, I was put on hold and then hung up on by that agent and switched to someone else. I spoke to around 4 or 5 different people before the accident took place. Each time I asked for them to explain the difference to me, I was pushed to someone else. They also refused to let me talk to a manager. I thought something was up when the amount of data this new offer included changed from 500mb to 600mb. 

It was after I got switched to someone else for the final time while I was trying to get to the bathroom that I lost my balance and fell down my entire flight of stairs.

The worst part? I just had a major surgery at the beginning of February where they removed my hip joint. I've been using a walker ever since. 

This meant a trip back to the hospital and more medical bills that I cannot afford.

I then paid my bill but my account still shows the same balance, now only "past due". I took screenshots to prove I paid it.

I can't just leave it and hope for the best because I have a cardiac home monitor that has to be connected to WiFi at all times. If I lose my service I could literally lose my life.

Also the Xfinity app said it was downloading my chat transcript but it did not and has not for a while I discovered. I screen recorded the chat though, just so I would have proof.

Oh and the "deal" would have ended in me losing more than half of my service for only an $11 discount. 

If they're going to cut my service in half, shouldn't my bill be cut in half as well?

This is going to be my last attempt at dealing with Xfinity which is why I am here [Edited: Inflammatory]

I already have quite the following and after the last ordeal my email was flooded with messages from others who experienced similar or way worse issues, [Edited: Soliciting].

I don't want to do that though! I just want to live my life with as little interaction with Xfinity as possible.

Please tell me someone can help me.
