Is HMD FX a scam, or is it legit?

I signed in with hmd investments llc 140 thousand₺. I made a considerable profit with the help of investment advisor. It's in the pictures. Then, when I wanted to withdraw this money, I was asked to deposit extra money under 18% tax + dividend. After that, I did not open a transaction for a long time, and then the person he claimed to be an FCA expert contacted me, supposedly came to audit FCA. The company does not have an FCA license. I contacted FCA via mail and provided this information to them, and it turned out they didn't have a license. Now, because I filled the trading volume, they would not receive dividends and if I switched to another price provider, I could only pay $3400 to withdraw my money. My finance expert is Süleyman UĞURLU and the other person is Özgür Bey who contacted me first. And if these people actually exist? My phone was broken, I lost some information. But I took some screenshots. After the earthquake, I sold my vehicle and entered the forex market with this money. I was planning to build my house with my earnings. It was all lies. Now I'm on the minus, not even at zero. I hope they won’t pocket the money they took from me.
