Unable to withdraw

There are so many barriers when I wanna withdraw funds in OANDA. First time is wrong bak card number and margin is needed. And then administrative expense is neneeded for the huge amount. And then the customer service said it took time from overseas account to Chinese account. But after a period of time, handling fee is needed. I deposit over 200,000. It's a judgment on me for my greed. This is a fraud platform. And I wanna ask OANDA, why do u allow a clone firm of u to cheat others? It ruins your reputation. Expose this platform to avoid more people cheated. OANDA should step forward and give us an explanation
