Why money didn't stay in payoneer?

Ahsanay

Hi, I made a withdrawal of $52 from my Fiverr account to my Payoneer account. My bank account is attached to my Payoneer. I was expecting that money will come in my Payoneer account and will stay there, but to my surprise as soon as money reached in Payoneer, it sent money to my bank account. I want to know why this happened? I wanted to keep money in Payoneer and then withdraw it to my bank account later when I wished.
Please let me know this.
