Advised by who?
Curacao eGaming is a joke, it's like IBAS in the UK, they would never side by you and even in the extreme case they would side by you their decision won't force anything.

Please, do yourself a favor and take advice from someone who knows how these things work.
You don't need Curacao eGaming and certainly don't reach out to them because legally it would put you in a lower position as they could decide against you and SportsBet.io would use it against you in court!

You lost a lot of money, not just $1000 or $2000 - nobody is going to give it back to you "as a good faith", it won't happen, so forget about it.

The only way for you to get your money "back" is via court or a legal action.

Please,
Don't dig yourself a deeper hole than what it is.

I'm going to PM you.
