Is it possible for you to post that proof? There is no need to start talking about international lawsuits but if you post evidence here you will bring credibility to your claim about being scammed. Unfortunately on many occasions people make scam accusations but do not provide evidence at any stage therefore their claim does not get the traction they had hoped for.
I have proof of a crypto transaction I sent from Coinbase to Unnamed Exchange.
I don't exactly have the means to start an international lawsuit though. As much as it is, a lawyer would cost more in no time.
