Withdrawal is unavailable

At first, I was asked to pay 50% of the money in my account to buy an unfreezing certificate as they said there were some errors in my credit card information. After I deposited 362,000 into the account, I was told to pay cash deposit for the money in my account was over one million. Then I deposited over 200,000 in the account, but it showed me password error and froze my account. I needed to pay an unfreezing fee of over 260,000. I was speechless! Since I have deposited much money in the account, I want to withdraw them out. So I did again! I managed to pay what was required, but was told my account was frozen again because either my account was showed in the system to be logged in from different locations or I went through unsafe websites. I was required to pay 50% of my money in the account to resolve all risks. I was cheated to death. Now I owed debts of millions. Many chatting records were deleted. For I want to withdraw my money! What should I do?
