Billing fiasco

Let me start by telling you that my bill is due on August 16th. I have been a customer of ATT since 1973 for home phone, 1991 for wireless and 2010 for Uverse with no late payments on any of the accounts ever. On Wednesday, 08/12, I received an email stating that my payment has not been received and when can ATT expect payment. This morning I received a recorded message that my payment still has not been received and I need to send it in ASAP or call and make payment arrangements. So I call the billing department to find out what is going on. The rep didn't have a clue as what is going on with my account (typical of a script reader). She tells me that it is collections initiating the call and email. I asked to speak to a supervisor and got the "typical response, no one is available but she will have someone call me ASAP". That was at 10:22 this AM. Still no call (why am I surprised by no call, that is the ATT way). The whole time that I am on this call the rep keeps telling me that I am a valuable customer. This is a heck of a way to treat a valuable customer. I did check with my bank before calling and my electronic payment was sent at 3:22 AM.
