bet11888 suspended an account with a balance without explanation

Hello. My name is Irina Ryvun. Made transfers to the bookmaker bet11888 (iTains N.V.) via Skrill. After a few days of playing with the bookmaker, I requested money from the bookmaker to my Skrill account. After that, the bookmaker closed access to my account, which contains 3671 US dollars. The bookmaker did not request any of my documents for verification. Nobody tells me anything at all. Just blocked the account without explanation. At the same time, he reports nothing, does not comment on his decision in any way, does not make any contact, does not respond to e-mail. It's just theft. Please help me get my money back.
