I don’t have issues with them either. I switched from Sprint to AT&T and have not been sorry I did.
I have Sprint for wireless, and have had a good experience with them. I deal with them as a business account however. My nightmare was with MCI World of Incompetents. When I had my service initially set up when I was in Albuquerque, they gave me a phone number in Grants, NM. 100 miles away. They corrected it the same day, however still insisted on billing me for two phone numbers.
I ran into Bernie Ebbers into the airport one time, before he went to prison. I asked him if MCI stood for Maggots, Cluster****s and Idiots. I asked him which of the three was he, or if he was a combination of the three. I sounded a bit like R Lee Ermey in the exchange.
In my closing letter to MCI, I told them to do the marketplace a favor. DIE!
