Att was destroyed as soon as they sold to cingular. I worked as a billing call center rep for Cingular when they bought them. The spent millions to rebrand everything with AT&T including signs at small ballpark fields etc. They had a bounty system where you could get paid if you found an old AT&T sign that hadn't been converted. About six months in they realized that Cingular's brand was despised by customers and that AT&T was really well liked, at least on the cell side. As someone who had to do plan conversions it was obvious that every Cingular option was a huge downgrade compared to the AT&T plans. Across the board their service was worse, their plans were worse and the customer service we were allowed to provide was worse. Finally they decided to convert everything to AT&T to try and salvage their brand. Overall it worked for a little while I think. But ever since working for them I have never and will never be one of their customers. They were a truly awful company to work for and tied our hands when trying to help customers.
