I filed a witness report with the Singaporean police and included their entity name and number FINANCEFIRST PTE. LTD. (UEN 201706635G), their supposed Singapore address (107A TAMPINES ROAD #04-07 THE TEMBUSU SINGAPORE 534009) and their Ethereum account (https://etherscan.io/address/0x297b79fe04691363bb9a74acc1414c7d80ebea2b).

I doubt they will find them but it takes less than 10 min to file the report and you only need to leave a email address: https://www.police.gov.sg/iwitness

Even if the funds will probably be lost the legal entity (which does actually exist, I checked) and their officers can be fined and possibly jailed (hoping for the latter).
