Unable to unlock mobile phone due to an outstanding balance that I apparently don't have
A few weeks ago I canceled my mobile phone account with AT&T because I've moved out of the US. I paid an outstanding balance (of $0.04) last week, and the AT&T site now shows that I've canceled the account and that I owe nothing. I'm trying to unlock my old phone, but I'm repeatedly told that my unlock request was not approved because I have a past due balance on my account. If I follow the link in the rejection e-mail, I get taken to an AT&T page which says: "This account is canceled. No further payments are needed." Would anyone have suggestions as to what I need to do to unlock my phone?
