I was going to Mexico and told the ATT support to not allow any of my lines to be charged for international calls, and requested none of the lines be able to take or make international calls. 1 month later, I receive an extra $100 additional fee for international calls to my already inflated bill. At this point, I begin the many calls (2 calls a day for over 2hours wait) to ATT in attempts to rectify the false charges. I was given phone numbers to unified *******085, which led to the ATT automated system hanging up on me every time I called. Another time I was told that there is an International dept that can assist me, and there I was also told they have placed a claim but I never heard back from them. I called in for a few more weeks, until finally after many threats to call my attorney, and creating a class action lawsuit, did I finally get told the money will be refunded. I am still waiting for the money to be refunded. My advise if you are considering ATT is find out how much your time is worth, and forfiet all of it to ATT because that is what you will end up doing if you have the misfortune to become their customer.
