charge for PPV events not ordered - DirecTV

I have been billed for 2 PPV events (UFC Fights) in Nov and Dec 2016 that I did not order or watch. AT&T credited my accout for the first event but now after it happened again will not offer credit for the 2nd event and is claiming what happened to me is not possible. In searching these AT&T forums I have found multiple other posts about the same billing error which I pointed out to a Loyalty Dept manager yet AT&T still claims it is not possible for me to me billed for something I did not actually order. Has anyone else had this probelm?
