How to recover money from a cryptocurrency company who keeps asking for more money?

What is the best way to recover money from a cryptocurrency exchange scam?

The platform I'm using to trade cryptocurrency is based in Dubai and operated by Chinese people. I have invested 100k AED into it.

When I wanted to withdraw money, the customer service said that I needed to pay IRS taxes on the profit amount.

After paying IRS taxes to them, they are now saying the financial intelligence department found that my account is abnormal and suspected of money laundering due to recent frequent trades and excessive TXN volume.

They want me to deposit 30% of my account amount (8k USD) within a week to prove that I didn't launder money, or it will be frozen and they will report me to the FI dept.

I don't have money anymore to pay them and I think it's just a scam. The platform recently had the system upgraded and changed; no license, no T&Cs, no physical address, no phone number.

Do I report to the police now?
