What is the best way of recovering money from crypto trading account?

I had recently befriended on social media a person from Hong Kong who told me is on a visit to Dubai to help her uncle who is a veteran in crypto & crypto futures trading!

During our communication, she told me her uncle & his friends have developed a strategy where they can predict the movement of prices at certain times which she regularly used to show her profits made!

She encouraged me to open a Binance Ac & a Trading Ac in https://www.metatraders6.site/wap/#/ (This site had an HTTPS & secure site certified by Cloudflare Inc) thus started trading 1st with smaller & then larger amounts!

I recently got doubt & tried to withdraw $3K money USDT (I have $ 15K USDT & visible in site) BUT couldn't. Now they are asking to deposit AED 23K for opening membership!

I'm now sure it's fraud BUT don't know how to withdraw. I also don't know where the website is located (CloudFlare can give the details as it's a secure site BUT need to approach legally).

Any help?
