Goth N' Rock They screwed up the order, but don't provide return shipping Konstitucijos, Lithuania

I ordered a pair of shorts online from them. They sent the wrong size. They are unwilling to pay for return shipping despite their mistake. They're only willing to provide a refund if I pay for return shipping, but it's going to Lithuania. It's not even worth it to return it at this point. And then they offer to give a 50 percent discount for the right size item. One day they say they have it, but when I pressed them for specific measurements for the item, suddenly they no longer have that item. I wonder what size item they would have sent if I did not ask for more information. I guess I need to sell my item on eBay now because of idiots who are in the business of ripping people off.
