I once was on the phone for hours with Time Warner Cable about a $50 security deposit charged twice, that was a mistake on their side. Turns out I was paying someone elses bill! At the end I explained to the supervisor that I will keep calling back until they fix this, not because I don't have $50 to spare, but because this is their messup and it's a matter of principle. They put me on hold (for about an hour) until their technical team fixed up something on their billing system. It's a pain to do this, and most peoples time is worth more, but if noone does it, we will be (in fact we already are) living in a scam society, where everyone is making money on everyone else's lazyness to track things down. When you call in, you are doing good not only for yourself, but for the company as well as every other customer.
