billed after canceled service

I am reaching out in hopes that this is an avenue in which my concerns will be addressed instead of ignored.

I called and cancelled my Xfinity internet service on August 18, 2026 and did not access the internet past the end of that billing cycle. Even though I was told it would be taken care of, Xfinity continued to bill me since and I have now been getting daily calls from the billing department. I tried to explain that there was a mistake on Xfinity's side, that I had cancelled the service, but I was given rote answers and was told 'my service would not be turned back on until I paid the bill'. 

I reached out to customer service on October 28  . And they demanded a confirmation number from my original cancellation which I had not been given. At the end of the October 28 call I asked them for a confirmation number to prove this phone call had taken place and they refused to give one to me. They told me they could not help me and that I must go to an Xfinity store and they gave me an address. I went to the address they gave me and it was an empty parking lot. I found another Xfinity store and made an appointment for the following Saturday morning. The appointment was not honored by the Xfinity store. I was told they were too busy and too short staffed to honor appointments. After I explained the situation they said they could not help me and gave me an address for a third Xfinity store. Once there I spoke to a very polite service agent, but was again told that he couldn't help me and that I had to speak to a corporate virtual assistant. The conversation with the corporate virtual assistant confirmed, and they could see, that I had not used the service in the months since I had called to cancel the service. I was under the impression that things were finally being resolved and was told to watch for an email to confirm the status that I had indeed canceled the service months earlier. 

Instead of receiving an email confirming the situation was resolved, I got an email saying the 'ticket' that the corporate virtual assistant had opened while I was in their store had been closed with no further details. I went online to check my account and it still stated that I owed several hundred dollars and that my service was discontinued for 'lack of payment'. I also continue to get approximately 3 calls per day from the Xfinity billing department. 

Xfinity, I want specific steps on how you will correct this situation.
