Comcast Signature Support $79.95 to talk to incompetent "technicians" nationwide

I called Comcast because I was having troubles with my internet connection and was transefered to Comcast Signature Support. They told me that I'd be charged $79.95 to talk to a support technician. Due to a bad phone connection, and the CSR"s strong accent, I heard $7.95. Regardless I was outraged that I was being charged a fee to resolve a seemingly pedestrian Comcast service issue.

The "technician" that I spoke to was both unpleasant and unhelpful. They suggested that I reset the connection by entering a code on the backside of my modem. That didn't work. Then they suggested that I buy an ethernet cable, so i did. However, even though I told them that I have a Mac, they suggested I get an ethernet cable. I bought the cable only to find that it was not compatible with a Mac (you have to buy an apple adapter, which at that point, I was unwlling to do as I suspected it still wouldn't resolve the issue). 

I called Signature Support back and told them that my issue was not resolved. Then they suggested the option of sending out a technician for a fee of $97.95! That's when I discovered that I had been charged $79.95 even though my issue was not resolved. A week later I called Comcast to dispute the charge. I was told by them that I was not charged, but then I recieved my bank statement which indicated otherwise. Subsquently I called Signature Support several times requesting a refund.

They finally conceded and promised me that the charge would be credited after 14-days. Almost 4-weeks later that has not happened. I've called Comcast but Signature Support seems to be an entirely different entity. Signature Support billing is hard to contact and they don't return messages. I'm not a new Comcast customer but I am appalled by their greedy and duplicitous behavior of recent. My only power as a customer is to drop Comcast and to encourage other customers to take care and be vigalant.
