This 16 years Nigerian citizen used his school fees to play bet and was planning to win big amount so he can use it to solve other problems but along the line he loss everything and he went to the contact of the company and begged them to refund the money back to him because it is his school fees.
We don't know if the player is truly 16 years old. Anyone could claim he's 16 and can easily falsify his information online. Also, the gambling platform explicitly states in its terms and conditions that players must be 18 and above, and there's no way they would have known that he's underage. Being under age does not qualify him for a refund or any kind of pity, if he had won the bet, would he had returned the money that he was underage? Hell no! His school fees is gone and what happened should serve as a life lesson.
I agree the terms of service have no exception if they allow the minor for a refund there will be cheaters who will create a fake claim with fake evidence to present to the casino to ask for a refund, you cannot cheat the casino when it comes to their terms of service they are strict on it and they expect all players to abide by their terms, even if the child bring it on the court, the court will just deny the plea and will favor the casino for upholding their terms.
If the casino knows that a minor is playing on their platform they have the right to confiscate his funds as stated in their terms, this is to discourage minors from playing in casinos online and offline.
