Fry's Electronics Not what I paid for Roseville, California

I bought a mother board from the Roseville store last night and returned home in Stockton. When I opened the box it had a different used mother board in side the box I quickly called the store and explained what happened and they said just bring it back for an exchange.

After returning to the store a 70 mile drive they told me it was damaged and the sticker seal had been broken. I spent 8 min on the phone with them the night before and hours in the store trying to get them to make things correct to all the told me was to take it up with the manufacture

The sticker on the box is not the same other models of the same exact motherboard and the serial number looks tampered with and if I where guess its an inside job. I feel completely ripped of with no recourse and tried going 70 miles each way
