Caveat emptor I'm afraid. When it comes to eBay I always check feedback first and second check is on shipping method (no yodel, Hermes or undisclosed courier and definitely not eBay's delivery system!). Unfortunately this time, for whatever reason you maybe walked into a fail, granted though there's always random feedback conflicting but that's the best bit about eBay is you can check first. As you opened up a case you should be ok -I find these days there's no way to contact eBay or paypal, so you will have to go through the rigmarole of justification and messages saying eBay tried to make contact etc etc before any return payment, but it does come through in the end, to rather than before, when they would check for you while you were in the phone call.
