Sometimes, we tend to break the TOS just to enjoy gambling despite the restrictions but as we take the risk, we should also keep in mind that our funds aren't in a safe place. 1500 is still a huge amount but to be honest, it would be hard for you to recover it. VPNs aren't that safe these days.
Sometimes gamblers don't really think about the TOS when everyone is about to enjoy.
Everyone is having that thought that it's totally okay to break what's against the casino rules because they've ignored it and thinking that everything is going to be fine.
If it's a big amount that you'll deposit, much better to be aware of the rules like that simple usage of VPN. It's better to ask the representative before using it.
It is true that when people just want to have some fun most of the time they are not thinking about the consequences of their actions, but this is not the case here, according to what I can read in the op he knew that he was not allowed to play in that casino from the beginning and yet he decided to ignore this and do whatever he wanted, and then he tried to deceive the casino several times after that, so it is clear the op is at fault and he will have problems trying to recover the money he had in that account.
