that's weird, they said on one of their emails on the screenshot you provided that they never perform KYC client checkups and that they only need to verify if your winnings are legal to allow your withdrawal request to go through, then on telegram, the "manager" (aka MichealJet) ask you if you provided KYC documents to their verification team. I am confused. do they as for KYC or not?
On the 4 or 5 cashouts that I did successfully I was asked for no documentation....
I don't know what happened jetwin has always done me right until nowit is probably due to the huge amount of money you were about to withdraw. most gambling site does this to see if any foul play or rules are broken while you were playing. I've read parts of their ToS and it seems that even if they said on one of their emails to you that they don't perform KYC checkup, their ToS mentioned that they can request KYC if needed. have you tried providing documents for their verification team review?
the question is why they asking for too much fees instead of asking to verified the account ownership which is they only needed to confirm that the player who want to widraw is the same persons who play. Also country restriction since the players came from USA.
