The good news is that he might be able get a refund for all his deposits, because he was not allowed to used their services in the first place and therefore they are not allowed to keep his money. They have to give all deposits back. Again, this is from a non-lawyer perspective of my own countries laws.
Probably no refund if the friend was able to withdraw money prior to his KYC submission and the amount already covers all previous deposits. The player was already in profit at that point.

To be honest, I can't understand the ToS of these casinos. They block the most wealthiest countries but at the same time run promotions that are aimed to attract people from these wealthy nations, doesn't really make sense
It does look odd but I'm not surprised anymore. Curacao have approved the licenses of many casinos advertised here but the Government prohibits these gambling platforms from accepting players from their country.
