Cosmos Capital Victimized Me, Please Find a Solution

I recently deposited money and started trading under Cosmos Capital's consulting services, but during the trades I was repeatedly told I had made mistakes and was asked to provide collateral each time. In total, I lost over ₺1,000,000. After each so-called mistake, they demanded more collateral, and I even authorized the other party to manage the trades. Eventually, my account was reset for reasons such as "lot exploding" or "spreading spread," and when I asked to withdraw my money, they again told me I needed to deposit collateral. Finally, they sent me a contract requiring me to deposit an additional ₺210,000 as collateral, claiming I would then get a refund, but I no longer have any money. I begged them to help, yet they insisted I had to send more money. My life has been ruined, and I ended up owing ₺200 while trying to make ₺100. We were in constant communication throughout these transactions, and I have all the payment receipts and correspondence. My customer number is 12346***, and I demand a full refund of my losses along with compensation for the hardship I have suffered.
