Profit cannot withdraw

I used the new customer of FUMENG platform to open an account as a free deposit, and 100 us dollars as a deposit.The account number is 687418. When I opened the account, you told me that I could withdraw cash if the accumulated number of transactions reached 20.Now that I've accumulated 20 hands of trading volume, unable to withdraw cash withdrawals, ping said Taipei I part of the deal is the hang seng index in Hong Kong, the hang seng index in dollar terms, not in hk, I haven't seen which platform sufferer not dollars, and I do hang seng, margin buckle is hang seng, loss of buckle is hang seng, when once settle for hk?When opening an account, they also did not say constant index is calculated with Hong Kong dollar.I think they are looking for an excuse to cheat.The platform customer service number is 0042036087658
