A few months ago I was contacted by someone from TRADAXA.COM , a forex broker promising very good results . When you open an account with them you can get a Payoneer prepaid Mastercard . they promise you can withdraw the money on your tradaxa account via the Payoneer card.
When I got my card ( with SISMACAPITAL logo , Tradaxa is a subsidiary of SIMACAPITAL) I wanted to withdraw some money. Each withdraw I tried was refused while my account had enough money. I found out on the AMF website that SISMACAPITAL is a blacklisted broker.
I contacted Payoneer support but after 1 month the only answer is " your inquiry is under investigation" .

Either Payoneer / Mastercard is complice of these people or they have been duped and they must pursue the scammers.
