@galadrel I sympathize with your issue and my opinion (as a long time Wise user - let's hope I don't jinx myself!) is similar to others here. Your personal Wise account (in Wise's mind) needs to be used for
personal use only, understanding that you're a small-time web developer taking in occasional pay for whatever big/small jobs you did. "Personal" use in their mind: convert your USD/EUR to whatever currency, send it to your (own) bank account in other countries, or to your aunt in Timbuktu on a monthly basis, use their Visa card to pay for something (legal!), top it up from your own bank account, rinse, lather, repeat.
Payoneer, on the other hand, is a complete opposite. They DO NOT want you to use it for personal purpose; if your Timbuktu aunt feels like paying you back (to your Payoneer account), they WILL reject it. They want you to use it strictly for business - they want ALL your payees to be a business (that doesn't belong to you, if they can somehow prove it). Connect it with Stripe, PayPal, Amazon, whatever. It sounds perfect for your web development gig. Payoneer isn't "cheap" but it works (for me).
And goes without saying, never the Twain shall meet, keep your business business, your personal personal.
Good luck with the "appeal", go email the CEO maybe, at least to get your money back.
