What do you expect when you are gambling on casinos that have zero presence here in this forum, most of those casinos deny gamblers the ability to change their details even when they have proven themselves, such casinos are doing that deliberately and most of them have records of scam accusations against them, so for sure you should be able to tell whether or not you have any chance to withdraw your money from that site or you wait endlessly for the response, your mistake is that you selected a wrong region while registering on that casino.
It is not my fault.I told you already I cant even change Nathionality by myself to do it I need to contact support which doesnt care.When I was creating account I was not even able to choose Nathionality which need to be added to profile to be able to withdrawal money later.
Wait, have you already completed KYC verification on your account?
Because if you’ve done it and passed, then the information you submitted especially your nationality should be final. Your phone number can be changed, of course, since we sometimes run into issues with it. If the casino is legit, their support team should be able to help you with that.
But if you believe you’ve complied properly and it’s their fault, then it’s best to create a scam accusation against them.
