IG is a fraud and gave no access to withdrawal

I was introduced to invest in IG by a guy called Wen Zhang on July 23 and Wen Zhang said I would be leaded by programmer so I must profit. I will be charged commission after profit by a percentage. So I deposited 90,000, the programmer help me invest. I was told that my account had risks at the first time I withdrew. I was asked to pay margin of over 170,000. Then I was asked to charge 58,000 to upgrade my credit for my credit score wasn’t enough. I didn’t pay. My account is frozen now.
