I’m highly disappointed

Hello my name is [Edit: Removed Personal Information] , I have been a Xfinity customer since 2024 ever since I became a member I have been mistreated and prior to me becoming a Xfinity customer I had a lady that portrayed herself as a supervisor trying to plant another customer account with my email address and also tried to tied me with their bill due to me having the same email address , moral of the message is that ever since I got with Xfinity I have been getting the run around . First , it was okay I was able to get service but they cancel the service due to management thinking I knew who another customer was and I had no clue who she was talking about . Second encounter I was trying to add another line to my Xfinity mobile account they restricted me stated that I had to pay full price for a new phone because I already had three lines , Third  encountered was today I called in about my bill which I been paying the same bill for 3 months and now my bill for this month has went up , I used the chat feature but that agent didn’t have a clue what to do . So I called the customer service line to speak with a human , I get the agent on the line , first I asked the agent why my bill was so high , she explained to me that my services was under a promotion that only lasted for 12 months was not aware of that until today , then I called back since my bill went up I’m like okay then ima take advantage of me upgrading one of my devices but when the agent get on the line he ran my credit then told me I couldn’t get the upgrade until I paid off all my devices  so now that they ran my credit now ima have to wait 90 days so something told me to just chat with agent , the last agent I spoke to did everything right explained everything to me but I just didn’t have the money to pay the tax fees today so I didn’t proceed . But after I explained all this in this message today I would like for someone that is either a supervisor or account manager to reach out to me to make me feel better because at this point I’m highly stressed out and blood pressure is high
