Actually, you're very lucky you paid with a credit card. You can do, worst case scenario, a chargeback. Just notify your c/c company immed if you have any type of difficulty with store and their response, and they will initiate a chargeback investigation etc. Paying cash, you'd be pretty much at the mercy of the store but you're alot safer the way you paid. I'm hope you get it resolved easily and with no hassle!
