My bank refused to do a charge back
You can't make your bank do a charge back. This function is to assist with straight up fraud, not a customer service mistake. (Think spoofed or stolen card or if a vendor intentionally acted fraudulently.) While you may believe what they did is fraud, your bank will require that you provide the vendor with the opportunity to rectify the situation themselves. Trying to call back and giving up after a long hold time won't meet their standards. If banks started letting anyone unhappy with a vendor start doing charge backs, they would be doing nothing else all day. The issues you're describing has not reached the threshold for the bank to authorize a charge back.  Comcast has local and regional offices, and you could go in person to speak with someone. Maybe there isn't one near you. There are non-peak hours which wait times will be less. You'll just have to grin and bear it if you truly want the money back. Then, take your business elsewhere and post bad reviews online. Always keep in mind that when you eventually speak with someone, they will not be the person that messed up, and you should be overly nice and polite to them. I promise it will yield far better results than being surly and demanding. Another way to get Comcast's attention would be to file a complaint with the BBB. It might take longer, but I've had this work with big companies, usually with good results. Again, be nice to whomever contacts you. In reference to your recent duplicate question: Mastercard won't be able to help at all. They play no part in the transaction at all.
