Wise won't refund my money

My account got closed 3 months ago (they never said the reason but I suspect it's because I'm from Argentina and they don't take Argentinian accounts anymore). They asked me for a bank account to refund me my money (10k usd), since then I gave them 5 different bank accounts, the last one being from a friend who lives in USA. They always say that they tried to refund the money but got the money back.

What kind of scam are they trying to run on me and how should I proceed? I'm tired and it costs me a lot to make such an amount of money
