AT&T Terrible Customer Service Policy- No Service Is Better Than Service

My service plan expired and I couldn't use my debit card. I was offered Bridge Pay, and my service was connected. I went into the 611 customer line to pay my bill. My mobile service was shut off, because the two plans conflicted. I wasn't told by the representative that if I paid my bill before the Bridge Pay plan is complete my network will be shutdown rending my phone useless. I can't reset my pin, because they shut the network off to my phone. Supervisor Arron #V549WD8 and Manager Hazel JxjS4G9 wouldn't turn my service back on, but insisted on submitting a four digit pin to a phone rendered dysfunctional due to service being shut down. A policy change needs to be made immediately. When a customer has a service plan, but they conflict service is better than no service. A warning message from att should've been sent to the phone telling the customer to call att before the mobile service was disconnected. A policy change needs to take place. I plan on leaving att if my service isn't restarted. I don't have a vehicle to get to att store.
