CFA is a fraud company

I flew from FB to the LINE group, downloaded MT4, set up an account, and started trading. Mr. Morita was in charge and initially managed about 100,000 to 200,000 yen. He was told that there was a discount product for crude oil and he would definitely make a profit. But when he purchased 5 units, he was told that the transaction required a deposit. So please make a deposit in a minute. The table shows that 300% for less than 10 million, 400% for more than 10 million, 800% for 50 million, 1000% for 80 million, and 1200% for 100 million. On July 12th, I was told that I would be able to borrow 50 million yen, and without any explanation on how to repay it, it was paid before the contract was exchanged. It said that the operating funds could not repay the debt, so I immediately contacted the person in charge and requested to change the contract or raise the debt, but neither was done, and the contract was not submitted. According to records, it became 378 million in just over a week. When I asked people with investment experience around me, I knew that MT4 was full of scammers. It is rare for the principal to increase six times in a week, even in the US market. The person in charge, Mr. Morita, said that he would discuss with the president, Mr. Tanaka about how to pay from the operating funds. But on July 18th, he said that it was impossible. Even if I say that there is no contract, neither President Tanaka nor Mr. Morita will listen. Would you please arbitrate and make adjustments and only return the original 10 million yen to me? Don't need the rest of the money. Thank you.
