Interesting - called today to make a payment with a gift card. Number at the top of the wiki worked last month, but the card didn't work with the IVR, most likely because of a 2032 card expiration date (that's what the rep said). She then told me that effective August 1st the overseas call center was not allowed to take debit card payments, but offered up a new number. Called Jacksonville - payment went through on the phone immediately.
