I don't understand a 7.5% fee
I work for an online company called Appen. They sent me my first payment through Payoneer. It was USD 40, yet I only received 37. Automatically Payoneer charged me a three dollars fee, that's a 7.5%! I did not withdraw or convert anything. So why such a high fee? I've been searching information about fees and oh boy. There are a lot, yet I can't find any that reaches this 7.5%. Is it normal? What is this fee for? Could it be a mistake?
