Unable to withdraw since Nov 2.

I have 386 dollars left on my account. WhenI tried to withdraw I was told to deposit more and make my total money to 1000 dollars to successfully withdraw the money. I deposited 614 more and right after I requested for a withdrawal. it has been 13 days and they are not replying. I have seent severals emails and left tons of messages on their customer service but still no reply. Can someone help me please?
