Sorry to hear you got conned like so many others, sorrier to see that ebaypal is still in league with these crooks.
I had one of these a year ago, a fraction of the claimed memory, it worked for about 2 months.

My suggestion:
Immediately post negative feedback, use terms like "fake memory scam".
They will undoubtedly come back pretending that they were unaware of the "problem", they will offer some form of refund and if they do not do so at first and you hold out you will later get offered a full refund.
Accept the refund and agree to pull the feedback as long as they have been truthful.
If they contact you after the refund arrives simply direct them to any of the anti-memory scam sites.

The weird thing is that I have never seen these devices sold at a realistic price (with real memory), the whole design/production effort seems to have been directed at these scams and if the scammers are actually paying cash for these the base hardware can only be a couple of bucks, add 16gb real branded for say 20 bucks and you could actually have something worthwhile.

In between times I have found that older model Sandisk players can be obtained from UK and US sites quite cheaply so, as long as you do not expect camera, games and other crap you ought to be able to find a reasonable capacity music player than is not sold with a fruit logo.
