Refusing to withdraw money transferred from bitmart to bitkub and said that bitkub is a ponzi

I want to withdraw money in usdt from bitmart to bitkub, but the withdrawal is unsuccessful, so contact the support of bitmart why the strange symbol appears. In conclusion, I transferred it to a wallet that is suspected to be a ponzi, which is bitkub's wallet and bitmart asks for a screenshot and asks for personal information. Including asking where the source of my money came from and why to withdraw it. I deposited to buy pepe2 9000 coins over usdt and the value dropped to only 30% of the balance. How is it wrong when I lose and I will cut the loss? That there is strange behavior, claiming the police, claiming the prosecutor is crazy. Nonsense, if he is conscious, he can double-check that bitkub is certified by the SEC, so I think it's a scammer or not, even though I've transferred in and out many times. Since there's a problem this time around, there were only a few thousand left. Saw a warning that bitmart is unreliable, thought it was right this time.
