Can't withdraw money from GHC

I have made a good profit while trading my MT4 account in proper way but my cash withdrawal has been hold by the company (GHC) with an excuse that my account has been placed under investigation from any type of fraud trading. It says, the investigation will take 10 to 20 working days. After more than 20 working days and several formal complaint emails written to them, GHC email to me with a statement that my MT4 account has been involved in fraud trading and disabled my MT4 account.
