I see you have dealt with this issue before.
Payoneer have now confirmed they have sent back just over $200 to Upwork for me, that I had transferred to them some time ago but could not tranfer out from them.
In this case, will the 200$ sent back from Payoneer just show up in my account, or how does it work?
I checked with our Payments team and they confirmed that in your situation the funds will be reversed back to the Upwork account. You should see them on your Upwork balance today.
You cannot get the amount from Payoneer to Upwork. However, there are other ways to get your money from Payoneer. You can transfer amount to someone else's account and get it cashed from him or you can transfer amount to your local bank account from Payoneer.
