These been quite a few scams over the years, like that XBox one tunnie mentions, and quite cleverly worded to mean that refunds via paypal are impossible.
I've said it loads of times before, never buy or sell "risky" items from/on ebay, as the scammers know all the workarounds.
"Risky" - high value electronic goods, such as mobiles, laptops, tablets.
Whilst there are still a few remaining genuine buyers and sellers, ebay has unfortunately succombe to a combination of intentional scammers and retards who should really be allowed anywhere near the internet. And a mindset has developed over the past 3 or 4 years that its OK to sell shit that is fake/doesn't work/misdescribed etc, as "everyone else is doing it".
Aside from exhausts and some items of cheap tat (that I knew was tat before buying, but just needed a cheap item for a specific task) absolutely everything I have bought from ebay in the last 3+ years I've had a full refund on via Paypal. I try to avoid the place, along with Amazon Marketplace and play.com (now they no longer sell anything themselves).
Who knows, maybe the High Street will make a comeback, as I can't be alone in getting fed up with this shoddy service?
