2. 1xbet changed my country to Bangladesh deliberately and refused to change it back to IRAN by my request .
Despite of this, why you still opted to play knowing in the beginning they did such thing which is illegal? It's already a red flag to stay away to this kind of casino. They want you to keep playing on their site but will use the fact that your country is prohibited to gamble once you win.
3.i won many USD but everytime i won 1xbet refused my bets and every time i lost they were ok with it .
1xbet has a bad reputation here thus it's not surprising if they did such action. But why it took you 3 years playing on this site before realizing their shady actions?
