Yep, I'm having the same issue. Made a payment over a month ago. 2 weeks later and it wasn't processed on the website. I rang to make sure my payment had gone through and the woman on the phone said my account had a $0 balance and confirmed my payment had been received. According to the website, my account is now 12 days overdue... I think there's a serious sync issue with the website at the moment that AGL really should look into.
