Deduction of my money from a tripping server

I deposited $700 made $2500 , the broker decide to deduct $1133.56 which they had edited into my withdrawal transactions.When I inquired about it an agent said there was no such transaction .Now FBS is tryna fix stuff in my mt5 history . They say its a fixed balance problem but where is the brokers transparency.It's sad how fbs is so trusted , how I trusted them
