I want to withdraw, but I was locked eventually

I was added to a group through the line community that only introduced stocks and later changed to introduce foreign exchange. Because I didn’t understand the foreign exchange market, I was foolishly cheated of nearly 300,000 yuan. There are customer service and Mr. Zhang induced people to invest money on the GBE Forex platform to trade foreign exchange and used Binance to transfer funds. After three operations, I wanted to withdraw funds but got kicked out of the group. The above two people cannot be contacted.
