(...) the website was telling me my betting was restricted for some reason so I decided to make a new account.
(...) it would not let me place further bets so a few days later I just made another account.
What message was displayed when you couldn't place bets no more ? Because if it was a personal betting limit and you bypassed it by just opening new accounts, then this is not what you should have done

Yes I’ll be honest. It was a message like that that I had received. So I created a new account. It happened twice. But even so that does not give them a right to not reply to any of my messages and steal such a large amount of funds
