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 now
