Best Buy Sells Broken PS3 With Mismatched Serial Numbers, Denies Return

"Bought a PS3 from my local Best Buy yesterday. When I got it home I found out it was broken.

So, I take in my broken PS3 to Best Buy today, to replace it of course, and they refused to because the serial number on the console is different from that of the box. They accuse me of trying to trade back a different PS3 than the one I bought (I guess there are idiots that do that), in order to get out of paying to have it replaced.
