I recently moved to Hawaii, and canceled my service with Comcast on the 22nd of May. However, I received a bill today at my new address (which I gave when I canceled the account) that was issued on the 28th of May, for service after the date of cancellation. This was especially troubling after I had been told that I would be receiving a partial refund for the time I would not be using the service.
When I attempted to resolve this via telephone, I found myself trapped in a long phone tree which always dropped me to a dead end noting that I'd "called after hours." This struck me as a surprise, given that both the comcast.com webpage and my bill itself note that I can call "24 Hours a Day/7 days a week." I apologize for attempting to contact you on the magical eighth day that you aren't open.
All in all, I guess this kind of half-assed fucktardary is what I would have expected after dealing with Comcast for eight years now. I should have known that the same company who tries to "serve me better" by removing channels from my lineup and periodically turning off my cable modem for "upgrades" wouldn't be able to let me cancel the service in peace without trying to take even more of my money.
