When I received my most recent bill, it said that I was past due on a payment and changed $0.24 interest. When I called AT&T's customer service, a guy answered and said,
"Hello. My name is ****. My job is to make you a satisfied customer. What can I help you with?"Wow! I knew at this moment that this was going to go well. I explained to him the situation. He said that their online system does not always initiate the automatic credit card payment system. Then, without me having to ask for anything, he said that he would credit my account $1 and get the automatic credit card payments set up.
What wonderful customer service! I have called AT&T before with a technical problem, but the problem was not resolved so promptly. (The beginning of the conversation went something like this.)
