Is Doris a scam, or is it legit?

Initially, I was buying gold through Alipay and after adding him as a friend, he invited me to a trading signal group where they analyzed spot gold trends and 9999 gold. Soon after, he asked me to download MT5 and trade spot gold on the Doris platform. I expressed my lack of understanding, but he offered one-on-one training. I started with an initial deposit of $500, which gradually dwindled due to their trading signals and my inexperience. Subsequently, he enticed me by saying that if I deposited a few thousand dollars, he could manage the trades and help me recover my initial investment. Many clients supposedly did this and since they claimed to be a regulated platform, I trusted him and let him operate with my deposit. After a couple of profitable trades, losses began until my account was wiped out. This pattern of blowing up accounts happened several times before I realized something was wrong. Despite significant losses causing me anxiety, I continued depositing in hopes of recovering my funds but kept losing. Finally, he mentioned that there was a veteran trader with over ten years of experience who could trade on my behalf if I deposited a few thousand dollars. The pattern of consistent losses continued as before. Meanwhile, as I sought justice on another platform, there was a suspicious offer where Doris agreed to a settlement of compensating me $12,000 if I paid a $3,000 security deposit—a tactic I believe was orchestrated by both parties involved. My account with Doris was also banned. However, I have trading records, transaction details, and chat logs. All I want is for them to refund all my money.
