Normal transcation, but no withdrawal. Deceive my hard-earned money.

Originally, a trader came to a platform with friends to trade a few years ago. Each person made a deposit of about 30,000 to 50,000 US dollars. After making a profit, no money will be given! Now there is a total of 350,000 US dollars on their platform, and they ask customer service for inquiries, but they always shirk and refuse to give money for various reasons. I feel like I have encountered a black platform! Many friends' money is hard-earned money, life-saving money! It was hacked by their platform. The more the merrier. Hope to attract everyone's attention! Stay away from this platform!
