My Payoneer Refund is Missing After Account Closure

I'm having a massive problem with the refund of my $500. After my Payoneer account was closed, a refund was supposedly sent from Amazon.com. However, now Amazon is claiming the payment was completed, while Payoneer is denying any knowledge of such a payment. I'm caught in the middle, and my $500 is gone!

I've already contacted both parties no less than 20 times, and I am completely exhausted from this endless runaround. The lack of clarity and the sheer amount of distress this has caused is utterly unacceptable. This isn't just an inconvenience; it's a significant financial loss due to Payoneer's inexplicable failure.

Payoneer, you need to fix this immediately! Locate my missing $500 refund and ensure it is credited to my bank account now. Stop denying responsibility and provide a clear explanation for where my money went. This ambiguity and the resulting financial hardship are intolerable. I demand a swift and satisfactory resolution to this frustrating ordeal.
