My parents have been loyal customers of AT&T since 1993. Recently they purchased a new vehicle with built-in mobile BT connections. So they wanted to upgrade their phone to a BT model. They were told that they could not upgrade their phone until the current contract was over. They weren't offered a new contract (which would have been bad anyway), they were told it simply could not be done. They were only asking to purchase a new phone, at full price, and transfer their existing service to the new phone. So they are going to wait for their current contract to end then they are switching carriers. Way to go AT&T! read full review »
