When proceeding to submit a U-Verse payment to my account. Two options "Checking Account or Debit Card". My choice was to pay via my checking acct. When entering my Name/Routing number/Account Number. then clicking continuing the Red Alert message came up stating "Invalid Routing Number" ! What! I know my Routing Number/account number by memory. . I have had this checking acct for over ten years. My routing number is correct. I attempted to enter it twice. "Invalid Routing Number" again! What is Invalid about it? How can it be "Invalid"?
