ARTA TechFin Broker Review

I had deposited a total of 66,000 in ARTA TechFin, but I cannot withdraw it now. Their company has a lottery event and I won 8888 US dollars and I need to deposit 5000 US dollars to redeem it so I deposited 5000 US dollars After redeeming the bonus, I paid the transaction fee as required, but their company refused to withdraw for various reasons.
