Hello.DeltaFX is not paying me my money.

Hello, I am a DeltaFX investor. I agreed with DeltaFX that I would not close any trades within 5-6 minutes and that I could make 20 trades in total. I made 21 trades. When I tried to withdraw my money, they said I hadn't followed the rules. All my trades were long-term, and I took screenshots. Which company can we trust to invest with? They confiscated my 1459 USD and are not paying me back.
