I did talk to customer service and they said there is absolutely nothing they can do until I submit KYC> They said no one has the ability to unlock my account except the security team, and they cannot talk directly with the customer.
I kind of made peace with the winnings stuck in there, and no plan at the moment to try and retrieve it via a mule.
$1200 is such a huge amount for people living in the third world and for poor people even in your country if you have no plan of withdrawing it you can just donate it to a friend who can try to retrieve it or continue playing until you lose it, you can enjoy playing that amount knowing that there's no way to withdraw it, but if I'm on your position I will try to withdraw it, if there's a will, there's always a way.
