Unable to withdraw. Expose the fraud platform

I was introduced by others to make money in foreign exchange. I heard that it was very profitable, so I contacted customer service to make a deposit. I was able to withdraw money at the beginning, but I couldn’t withdraw money later. I contacted customer service and let me deposit money. I won't be able to mention it in the future. I learned from the Internet that I was cheated. Now the customer service does not reply. Don't be cheated.
