Well, Time Warner just screwed me. I don't want to go through the whole story, but basically they kept my account open, after I told them to close it, for one day into the new billing period. When I called to complain, I was told that a credit would be issued to zero out the account. Needless to say, the credit was never issued and they are still billing me for a charge they never should have put on there in the first place.
Now they are going to send it to a collection agency, so I have no real choice but to pay it, but I sure hope to cost them a LOT more than the amount in question, which is 12.46.
Please do not get Time-Warner services of ANY kind if you have an alternative. They are corporate scum and had no compunctions about screwing me and then telling me that there was nothing they could do.
