Three years ago, in preparation for a short vacation travel to Canada, I called and asked that the "International Calling Feature" be added to my phone. Upon return to the USA I promptly called AT&T and cancelled the feature which was properly handled and I continued the arrangement where my credit card was automatically charged for my AT&T bills.
Recently I discovered that the AT&T accounting department erred and added the same charge to my second phone without authority. This second has never been out of the USA and the feature never used.
In a recent discussion with the wireless accounting department, I was told several things such as "they could only correct their error 6 months back" and "it was my responsibility to audit the bill each month", etc. Since I take advantage of AT&T's proposed paperless billing option which reduces costs and payments are received quicker I never had reason to audit AT&T's business practices since I did not authorize any changes to my account.
As the conversation ended, I was promised that a manager would call me within the hour --for which I patiently waited. The manager call never came and I'm told that that comment was recorded in my call record.
My reasonable request is that since I never authorized the charge and the feature was never used that AT&T refund 36 months of these charges.
