scam platform, homepage crash, can't withdraw money

I joined MTDFX through the invitation of brokers. Trading stable for a while with no problems, suddenly on September 8, 2022, the exchange suddenly couldn't log in to MT5 anymore and there was no email to notify about this problem. I asked the broker, they said that the floor is under maintenance, will reopen soon for trading, but today (September 12, 2022) the homepage of the exchange is mtdfx.com can not log in to withdraw money anymore. All previous transactions are considered as losing both capital and profit. The previous server of the exchange on MT5 is Cang Limited and can't be found now.
