I just had the pleasure of working with the most professional customer service rep I have ever spoke to (that not only includes AT&T, but any other customer service line as well). So a HUGE thank you goes out to Mr. Warren P. of the International Billing Department. His assistance was unmatched. AT&T reps, make sure you give him a big pat on the back.
Keep forwarding this message so he gets the kudos he deserves............
