Cancel AT&T Wireless from abroad
From March to September I have been in the US and have used an AT&T Wireless Service. In September I went back home to Europe. When I bought this, the representative told me that to cancel this I should just stop Autopay. Well, I did this but I have been getting invoices. At first I thought maybe I had to ignore those but as they starting including fines for past due payments I decided to pay it anyway. But the service does not seem to be cancelled. How can I properly cancel this?
