Complaint Review: ATT store and 50 and 405

My wife and I went into the ATT store at 50 and 405 in titusville on 12/13 to buy a ipad for the wife . Dion helped us and said while we were there we could both have a free phone upgrade and all we had to do was sell her us our old phones for 100 buck each and we would get free phones. We didn't need phones at the time but really free? How do you past that up? We were in an ATT store. They wouldn't rip us off right?  We traded in our phones that were working just fine for these new phones. The wife bought her Ipad with a 300 buck deposit and we would finance the rest. Well after about 8-9 months I asked the wife if our phone bill had come down in price as the ipad should be paid off by now. After reviewing the bill it appeared that they had charged us full price for the 2 phones.1200 bucks.. What? I went back to the store and one of the folks there said that Dion would call be and straighten this out as she was not there at the time. She never called. Huh...go figure. I want back to the store and she is not around again. I asked one of the sales people how could this have happened and he said" there are some sales people that lie and decieve to make a sale" What? And he repeated it again. I was floored. This is the way Att works apparently. I have file many reports through Att and they couldn't care less. They have lost my business in the future. I just wanted to let other folks know to be very careful dealing with these jerks.
