Pending Payment since 13 September

A client sent made a payment to me on 10th and it reflected on payoneer on 13th and have being pending till date.

I contacted payoneer through live chat and I was assured that the fund will be released before 22nd, but here we are.

The thing is that, this pending payment have stalled the project I have with this client and I'm not happy with it. I'm suppose to confirm this payment before we can continue with the project.

Can someone please explain to me what is really going on?
