I HAVE a post-paid Cellular Telephone Account with GT&T. This account has been paid up to the next billing period, April 14, 2013.

As of Saturday March 23, 2013, I started receiving the following message when attempting to make calls on my cellular phone: “Your account does not have a sufficient balance for calls to the dialled number. Please recharge your account first”.
Very surprising, since this is a message one would normally get on a pre-paid phone when credit expires. Further, I observed that I was not getting internet service on my phone, and that I was unable to send text messages. In total, I could receive only calls and text messages, nothing else. When I visited a GT&T office to enquire of this state of affairs, I was told that there was nothing wrong with my account, but they were experiencing some problems, and that there was nothing they could do. Sorry. Is that the best value for my money? Or should I  switch to the ‘Bigger, Better Network’?
