I received my Payoneer last month and I loaded few days ago using OKPay. With a mere $80.
First they took their annual fee THEN locked the card claiming that the source of the funds is unknown asking for documents to prove the purchase.
After providing screenshots of my OKPay account and the actual credit card withdrawal transaction, they replied, quoting their staff "I understand the funds are coming from OKPay.com, however this company is a payment company, and the funds didn't originate at OKPay, but came from a third party."
Still haven't unlocked my card, I submitted screenshots of my Payza and Paypal of all my transactions. I have no freaking idea what they want, a 100% legit company would have taken their fee AFTER the verification of the source.
