A blood-sucking platform, I lost 1.5 million, and the trading account did not allow me to log in. Contacting the customer service of the platform is just an excuse

In this platform l lost 1.5 million. On the morning of July 17, 23, I could still log in to the trading account, but I couldn’t log in at noon. I contacted customer service and they kept refusing. This is a black platform.
