How is it "without any explanation" when you know exactly what you did to cause your documents to be rejected? I don't think you can reasonably expect to be allowed to try KYC with different names until you pass. You may be allowed to correct a spelling error or a blurry photo or something, but not "oops, I'm not really that person, let me pretend to be a different person".
Anyway, no one here can help you. You may try to PM Stunna as advised above but I don't think jumping to scam accusations is helping your case. If he feels generous you might get your initial deposit back.
That is, in your opinion, it is absolutely normal that they let me make a deposit with a different name, but they don’t give me money to withdraw? From the point of view of humanity, is it okay to forbid me to withdraw even my deposit?! When my KYC is passed (in my humble opinion). This is a racketeering, in fact, to give money and prohibit withdrawing. What can we say about getting a winnings? After this situation, I hardly believe in it.
