Gamblers should bet on games that are familiar rather than looking for quick casino to gamble on without checking if their region is acceptable or not. I know that majority of us are guilty of this even when the casino gives a red flag stating that the casino is not allowing residence from such area.
I am confident that I have never played at a casino that does not allow players from my country. Actually, most casinos accept players from my country. So, I never had to sign up for a casino that does not accept players from my country. I would highly advise people not to use a casino if they do not accept players from their country. This way, they are risking their money and wasting their time as well.
You will never be able to accuse them because it is the player who violated the rules. So, you are unlikely to get any help from mediator services like askgambler forum.
Yep, they would point at the rules and politely say to get over it, or to speak to the support of the platform, which wouldn't lead somewhere, only if the compromise would be needed..
