Formal complaint

I reached out on 6/23/2026 to try and extend a payment arrangement I had due to the sudden passing of my wife. I spoke to a representative who told me they went above and beyond and got the arrangement extend to 7/12/2026. They cancelled the original arrangement.  10 minutes later I started to recieve collections calls and text. I told them the arrangement was made and I was told services are secure until 7/12/2026 i was then informed it was not a payment arrangement it was a promise to pay which doesn't secure my services. I spoke to another rep who told me I had to make a payment that night or my services would be disconnected.  I called and spoke to a supervisor about the information from the chats they said let me help. They placed me on hold I was then transferred to automated system and the call disconnected.  No one called me back. So I reached out via chat again at 6:08 pm and spoke to a rep until 8:30 and was told if I pay the past due is would be able to get the loyalty 50 plan. So I made the payment. I was then told collections would call me on 6/24/2026 they never called i chatted and called 6 times to speak to collections and was given wrong numbers everything. I finally spoke to collections and advised them I had 2 reps on 6/23/2026 guarantee me that paying the past due would get me the loyalty 50 only to be told by collections that because I made the payment online im no longer eligible.  So I call customer service to speak to a supervisor and advise them of the situation only to be told sorry about the misinformation I can do anything about that. I have chat id numbers, I have ticket numbers , I have screen shots of the chats to show all of the information I was told by the diffrent reps. At the end of the day comcast/xfinity knows they are the monopoly where i live. So they know we have no choice but to use them . I wasn't asking not to pay i was just asking for more time. Their representatives are the one that told me about the loyalty 50 program I had never even heard about it.
