So I sold a Razer Blackwidow 2014 (NEW) on Ebay, and it arrived on time and everything. A Day after it's delivered, I get a return request. At first I thought it was something I did, but then it occurred to me that Ebay had put the wrong information in the listing, because it was new, and there was nothing I could of done. His reasoning is this: http://puu.sh/rfEtj/ffc3738f4e.png
The number in the title is in no way false advertising, as its the same: http://puu.sh/rfETa/6297ad77e5.png
However, I suppose when I listed the item, Ebay took the liberty to put extra information for the keyboard that was completely false.
This is what Ebay did: http://puu.sh/rfF1Z/05e945fbcd.png
Notice how the MPN number is different then the one that it actually is, the one that I put in the title.

Here's the problem. I don't believe there was anything that I could do change that information that Ebay put without lying to the buyer. What should I do? What I advertised was what the buyer got, but what Ebay advertised for me was NOT what the buyer got. It would pain me to issue a return for something I couldn't control, (and something tells me the buyer is actually trying to return it for a different reason, but noticed that and took to that for his reason).

What should I do?
