Sega CD

I bought a Sega CD from a guy on eBay a couple of weeks ago, the listing specifically said 'express delivery', so here I am still waiting for it. The guy's ignoring emails. I've requested his contact details from eBay this morning and sent him a text to see where it's at. If I don't get any response by Monday it looks like I'll be going down the 'non-performing seller' route. Git.
