Bro, stop crying. You won't be able to do anything.
It is your responsibility to know your country's rules. Even if the casino does not follow your country's rules, you have to follow them. Gambling is banned in my country, but most of the casinos online accept players from my country. So what? It is my responsibility to follow the rules. This is nothing new. We see similar cases every other month. Someone from a restricted country makes a deposit and loses and cries, saying they should get a refund. Well, this is just an attempt to milk the casino. Cry more!
