Poor Service

During the last six month I have been disconnected 8 times now, where the first 5 times was due to call barring.The call barring was setup when I was migrated from Nashua Mobile to Autopage and never properly explained. At first the call barring for the first 3 times was reset at the beginning of each month there after I had to phone the call centre twice to reset. I went in to Brooklyn store on the 8th to remove call barring limit and they could also not tell me what is causing this, same as call centre. By the 9th I could still not call, had to phone call centre again, had to reset my line again. By the 15th I was down again, had to call phone centre again to reset because line was suspended. Today the 18th I am down again, and up until now nobody can tell me how I have reached this call barring limit and now that it is removed I was disconnect three times again after that, there should be no limit anymore?. How is that possible? To me personally it feels that the support agents do not know how the system works and keeps on following wrong steps to solve the problem. I am really tired of this now and just wish I could stop this contract because nobody can seem to sort this out!
