It totally depends on Stunna whether Stunna will handle this type of case or not. If Stunna handles then I think Stunna will be able to help. Scammers never learn anything until the scammer loses something or pays something for the scamming. A few years ago someone gave me collateral that showed value on etherscan but that has no value actually later I got the same number of tokens and received more than owed by the scammer. Then the scammer learned how many mistakes the scammer made. Tried to get back the token but I have not returned it as there was no communication before that and the due date passed.
