Scam！Unable to withdraw!

This platform is unable to withdraw, but they said that their platform was legal. I wanted to withdraw USD 5,000. The employee in the platform said that the withdrawal had been processed. When I checked the account, there was no funds at all. The platform customer service had been missing. There was no user registration on the phone call to him, the account balance was zero, and the investment account funds were all gone. I won’t trust the platform anymore!
