Agents cheat customers with high fees

The transaction fee is not clear. I asked the customer service, and the customer service only replied that this is the current handling fee, not mention the specific amount. I asked the customer service for the agent's information, but didn't say a word. For each transaction, the platform will deduct a handling fee of US$50 per lot on behalf of the dealer. In addition, the platform will deduct another $50 handling fee. The agent told us that it was deducted by the platform, and the platform handling fee was 100 US dollars per lot. In more than half a year, the agent's handling fee was deducted 10,000 US dollars. And I also lost more than 100,000 US dollars. Strongly request the refund of the handling fee deducted by the agent, and request to bear a certain amount of damage compensation!
