I have received the best customer service at the AT&T store near Chapman and Main in Orange, CA. The store manager, Aaron and the assistant manager, Arlene, spent a lot of time resolving an issue I was having. They were knowledgeable, personable, and patient with my many questions. It was all taken care of without making me feel rushed. It's the kind of customer service I always wish for, but don't always receive, and it is much appreciated.
