I was just on the phone with Worldcom Wireless Customer Service. I've had them for just over 2 years. I got a great deal for back then and a free Nokia phone. Anyway, I just called to cancel my service and was told I couldn't! I had just asked her who provides my service and she told me AT&T. Then she says sorry, but all our AT&T accounts are locked at the moment. She said they are planning to contact us all in 2 days. She didn't know what that was about or wouldn't tell me at least.
