LION BROKERS, is an unscrupulous platform and doesn't allow to withdraw

LION BROKERS, is an unscrupulous platform. When i make profit, they didn't give money and directly close the background. The company said that the customer violation of the transaction. I don't even get a notice. I asked them to provide evidence. They didn't provide it and said they would not send an e-mail to the customer to explain, there is no such practice. They also said that I have signed an agreement that only withdrew the principal. I have never seen this agreement, how did I sign it? Everyone stay away from this platform, it is a fraud, all kinds of scamming ways, certainly do not give the profit!
