Xfinity Comcast False charges for non-existent equipment, fake requisition numbers, fake call-backs, no refund Hollywood Florida

Xfinity added charges to my bill for cable boxes which don't exist, from Jan 2017. I noticed in February, and have called repeatedly and was told it would be fixed. It never was. In August I called again, and the CSR removed all future charges, but  she needed to issue a ticket for the last 8 months @$20/month plus taxes and fees  which still needed to be refunded, totalling $160. The CSR issued me a requisition ticket # of 043518793, and a promise of a refund by 9/10/17 and a call back tomorrow for verification. Also she scheduled a home visit for 9/2/17 to install a new cable box and check the house for equipment. 

Nobody came and no refund. We rescheduled the visit, he came to the house, inspected our rooms, and veriifed that we've been overbilled for months and that we didn't have all that equipment that we were being billed for. 

I called again...and again...and again...and 3 online chats. Everyone apologized for the no call back and scheduled new ones, and verified that the refund was justified and scheduled for the next billing cycle. NOTHING. 

On 11/2/2017 I called for the 8th time, and spoke to Qunique. She said that the ticket # was wrong and gave me a new one # 044362302, promised a call back tomorrow, again..but that refunds only go back to 90 days! That would mean zero! The charges were from Jan-August..it is now November. I have been calling since February! 

These people are either useless or liars. I want my $160 back and stop adding imaginary charges to people's accounts. I have reported them to the FTC and BBB today as well. Idiots and I'm trapped with them because they have a contract with my condo. I'd switch companies in a heartbeat if I could.
