Xfinity x9 my service fee, ignored my cancelllation request, denied my refund request and robbed mY AUTOPAY!

I just left this as a review on trustpilot as well as your customer service agent was unhelpful and refused my request for a supervisor, stating they were "unavailable".

AVOID XFINITY AT ALL COST.  STRAIGHT UP BANK ROBBING THIEVES!!!!

I just spent 45 minutes to find a way through AI to speak to a customer service agent that was unhelpful and refused my request for a supervisor, stating they were "unavailable".

Xfinity robbed me by multiplying my service fee 9 fold from an authorized 10$ a month to a ridiculous 90$ a month. I spoke on Jan 2nd asking for a refund for Oct, Nov and Dec and to stop robbing my bank account with autopay. I was given an [Edited: Personal Information]. That was completely ignored and my account continues to be billed 90$ a month despite me having dropped off my equipment at an xfinity store ( which they claim "not received"), asked for a cancellation and having revoked my autopay, and me having moved out of state. 
I just saw they had sent an email in Jan saying we cannot refund your request. I now see they ignored the cancellation and continued billing despite me being out of state and having given back the equipment.

 I'm being told now in February that there was no overcharge. They also refused to refund the overcharges from October and say I "still have their equipment". DO NOT GIVE THESE PEOPLE AUTOPAY. THEY WILL ROB YOU!!!!
