How do I verify my identity to avoid further confusion and delay.

I was sent a payment from a customer using the Global Payment Center. When the money arrived Payoneer requested some information from me to verify I was who I said I was. I sent a photo of my passport and my current address. Payoneer then returned the money back to my customer. I do not understand the verification process, I have an active account with Payoneer.
