Lied to by Xfinity Mobile Team and they refuse to resolve the issue.

I want this to resolved so I'm posting here. A year ago I spoke with chat to lower my bill. Their option was to sign up for an Xfinity mobile phone at no cost to me which would lower my bill. They told me to activate it and put it in a drawer since it's free. I stupidly signed up for this. 

A month later I started to notice charges for xfinity mobile outside of my internet bills. I would start a chat with support and they would reverse the charges saying it was a mistake and I wouldn't receive another charge. At somepoint I stopped and fighting because I was in an accident where a car struck me as a pedestrian, but the bill went up to over 50 a month. I immediately started a chat, renegotiated my bill and was told I would received credits for what I was charged. This sadly was not the end.

Two months later notice I'm still being billed 8 dollars month and was never given my credits. I started a chat today I'm still on and I'm being charged 8 dollars a month to pay off the phone I was told that would be free to me. They're also telling me there is nothing they can do to resolve any of the charges and it's Xfinity policy to not reverse charges or give any type of charge to make whole on what I've paid I never should have. The credits they gave me from the last phone call are on the Xfinity mobile charges I'm no longer paying and they cannot be used to on device payment.

This is horrible business practice and I've been lied to every step of the way on Xfinity mobile. No one will resolve the issue and I'm being told there is nothing they can do. I would never use this company again if they didn't have an internet monopoly where I live. I'm posting here in hopes someone can resolve my issue or else I might seek outside resolutions. It seems there are a lot of us who have faced this issue but to be robbed up around 180 dollars and a lot of time chatting is insane.
