We just spent a wasted half hour on the phone to the AT&T Yellow Pags to complain that we did not authorize a renewal of our display ad. They claim that there is a line in the contract that states that we had to have sent a written cancellation two weeks before the renewal date. They claim they sent a letter, which they did not. They now say we are liable for the monthly bill. Sounds like grounds for a class action lawsuit to me.
