****UPDATE****
Well I decided to try the eBay resolution centre via PayPal and put in a claim for my $17.99 HP SSD 500Gb Hard Drive.
I gave the option of wanting a refund and oddly within 10 minutes the refund was granted, no quibbles at all.
Admittedly my seller had been de-registered the day after I made the purchase and as such eBay would be totally aware of what went down in this instance, thus the quick refund and resolution to this scam.
Cheers,
BB.
