BEWARE OF BILLPAY especially if USAA says that they have a relationship with the vendor, thus not allowing you to enter the address where to send the bill. If they screw up (and THEY DID), YOUR ELECTRIC GETS CUT OFF while you think that the bill was paid and confirmed online in a timely manner! I had to make 4 phone calls to get to the bottom of this and USAA threw blame on their third party vendor, CheckFree PartnerCare. I had to pay $100 deposit, $40 reconnect fee, and late fees. I got my deposit and late fees back but not the reconnect fees from the electric bill. Fighting with USAA to get that back, but the Ex. Resolution is telling me that I'm being rude! Grrrhhh!
