UNABLE TO WITHDRAW

I was introduce by my friend (Mr Tan) to invest into this company “www.ruilong investment''so called broker. I have deposit USD2585 via bitcoin and transfer to my broker account number 101618 in Ruilong investment on 9 Aug 2021.The original investment plan is once i deposit and open account, the broker will trade for me on behalf ( fund management ) But today i have decide to withdraw and close the account due to i have cash flow matter . The broker give an unacceptable reason that ask me to top up more money (40%) from the initial capital before can i withdrawal all my money and close account . The reason they give is because my account was inactive just for few week and the account also is manage by the company . I suspect this is a clone and SCAM broker without any license or regulated . The previous company is named as Richness Empire before they change to RuiLong Investment . I believe the broker list i select (Ruilong investment) is a same entity that stated unlicensed in united states. Wan Qing
