I recently got a new credit card, and went into the Self Serve area to change my pre authorized payment information. I made sure that my mailing address matched that of my credit card, and also ensured that my card was activated properly (I recently changed my pre authorized payment method with my internet provider, and everything processed fine). When I inputted the new credit card information, I received the following message: UNABLE TO PROCESS REQUEST AT THIS TIME: ERROR 20. I tried this multiple times over the past couple days, and keep getting the same error message. I also tried looking up this error message but couldn't find what it means. I know that it costs $10.00 for changing anything via a service rep or *611 that could be done on Self Serve, so I was just wondering if anyone could help me out as to what I might be able to do to change my pre authorized payment without having to call in. I just want to make sure that my monthly charge will be paid on time and I don't get a late fee. Thank you!
