Double Billed for many months. Even the Xfinity agent told me to report the issue as fraud.

I have been billed by Xfinity on 2 different payment methods for months.  I have reached out to support over a dozen times and spend at least 2 hours each session with an agent.  Xfinity will only acknowledge one of the payments and will not accept the documented evidence that I can provide to prove that I am being double billed.   Each time I reach out to Xfinity that act as though they have no record of my problem and that I must completely start over describing the issue.  I typically spend 2 to 4 hours talking to an agent with zero resolution.  The agent typically talks in circles and then try to push an upgrade offer on me before mysteriously disconnecting from the call.  The last 2 agents that I spoke to just told me to report the charges as fraudulent which I have and blocked xfinity from charging my credit card.  Now I am receiving letters from xfinity  that I owe them money and will be sent to collections.  I felt that the amount of money I was frauded was not enough to justify getting a lawyer involved but now it looks like serious damage could be done to my credit and legal action will need to be taken if we cant get this resolved today.
