INVcenter is a ****

I have deposited in this company $200 about 2and a half month ago. So I have made $55 in the next two days. Since then I have been trying to withdraw my money and they don't want to give it. Then I was contacted and I gave them the documents. Now I still can't withdraw, but the best thing is that of the$255 that's in my account, I can only withdraw $176.36. This is absolutely ridiculous and absurd. That was the only money I had and they have made my life a living hell. Can somebody please help
