So, I just had this problem. They claimed that they double-credited me for an item I reviewed 5 or 6 months ago, and only discovered it after I had cashed out my account and stopped reviewing for them. They filed a dispute at Paypal for my last cashout, which was for around 3 times the supposed double-credit.
The dispute claimed that I had not delivered merchandise that they paid for! They are committing fraud by telling Paypal that I am a vendor and they are a buyer, when in fact they are reimbursing folks like us for buying Amazon items and providing reviews.
And the real problem here is that Paypal is complicit in this fraud. I provided documentation of the circumstances around this dispute, and Paypal promptly, and without explanation, simply found in their favor. Why? Because Paypal makes money off this fraud. They make money every time Rebatest pays a reviewer. And even worse, they make money every time Paypal finds in favor of Rebatest and charges back the reviewer's cashout.
I think it's time to get a journalist interested in this source of (often low quality) Amazon reviews, and in Paypal's part in the problem.
