Suspended my account immediately after depositing

I met a girl from Hong Kong named XIA YAO via Tinder, who persuaded me to invest on the broker. she successfully wheedled me into opening an account and making a deposit on the platform. But the staff has shut down the broker's website and changed it's name. The investor: At first I thought it was XIA YAO who would help me place an order, but I was wrong. She invited me to a WhatsApp group where an investment adviser was in. The adviser suggested topping up my MT5 account with €1 million and his managing my account. If I made a profit, he would take 10% commission from it, but if I lost, he would compensate me with 50% of the total amount. The investor: I made the transfer under the platform's instructions. Thereafter, I noticed that my MT5 account rejected me to log in and kept telling wrong password.　　I contacted the platform, but they insisted that they had not received my remittance.
