stopped operations,payment not done,account disabled


I have an trading account with and was trading with them since May 2013.But all of a sudden they disabled my account without informing me and ctting my positions making further losses just a few days since i placed a withdrwal request.Account managers dont pick calls,emails not answered by website nothing.I had made a loss of $250 earlier in July but now i was trading good and made $728 after fresh deposit.They cant do this to their valued customers.This is irresponsible behavior & unfair practice.I want to file a case to get my money back.
