Berndale Capital won’t let me withdraw my profit or log in.

I opened an ECN account on Berndale Capital with a number of 2096852678 on August 16th. They promised me they won’t fuck up my orders before I deposited $6000. I earned $3310 during that time. Then I withdrew $1500. After then I’ve been trading under the guidance of their customer manager and withdrew $3000 again. Ever since September 3rd, the withdrawal process became troublesome. I urged them but they said I violated their rules. I’ve all the evidence to prove my legitimacy of trading. I want them give my money back!
