Metro PCS online payment not acknowledged-cell phone turned off , Internet

I paid my Metro PCS cell phone bill online with Express Pay on the due date. Payment accepted through Metro's Bill Matrix with a confirmation code.  The day after payment, Metro PCS says my payment has not been made and my phone has been disconnected. Three (3) DAYS later, my cell phone is still not on and there is NO WAY to get to a live person. 888-8metro8 is a phone tree with no way to get to an "agent", event tho the recording says they will connect me to one if they can't help me. All they want is payment, which I already made.  I will be reporting this theft of my money to the credit card company and I will no longer do business with Metro PCS.  Calling the Bill Matrix service does no good.
