Prorated Cancellation charges

I reached out through the forum and got my Xfinity plan cancelled on March 11th. I even have emails confirming the cancellation request & final date of service.

i called Xfinity today (which was a whole nother mess. In the middle of chatting with an agent, it said the phone number was disconnected and no longer in service. Then, automated voices speaking over a live agent. A mess). The agent said the cancellation request which was confirmed through email, was CANCELLED. No idea why, as I did not approve of this + I did not get a follow up email that services were starting up again???

I got charged my full bill on March 11th of $73. My service ended on March 11th.

does Xfinity bill a month in advance? Should I be getting this entire amount refunded? Not to mention, the April bill is still popping up as to be paid.

I also keep getting an error everytime I try to add tags, and it deleted my post.
