Cash America Pawn

I put my game system on loan then can in the next month to put a loan on a tv. The store manger told me I extened the gane for the the same pick up time as my tv. Every thing was paid for then once I returned to pick up my brand new system that cost me $300 from gamestop which I have the receipt. The store said it was sold and that all they were going to give me for there mistake was a used beat up game system that they wanted me to pay for.
