IMHO if you live in a restricted country and made some deposit, Casino must give your deposit back. Casnio can look at your profit and loss history (if you have played before and cashed out) and decide how much deposit they should give you back if you are down.
I’m not aware that you have the right to request for refund for all your losses when you are restricted when you play while your country is restricted. I remember reading same comment before on one of scam accusation here which he use his country law as reference to his claim.
However, I’m wondering if casino really follows this since it’s very rare or I never find any casino that refund back losses. Only the deposit which in case the user end up with profit.
