Hi,
Sorry for your inconvenience, Even though I don’t like it but sometimes KYC is necessary measurement taken by almost every sportsbook or gambling casino out there. However, if the last part of the email you got was really sent from them, then that’s absolute bullshit, it’s bad enough that they change the wagering terms just after you won, please pm the their profile with a link to this thread. Reputable DT members will surely be following this and would do the needful if they’re found guilty.
