I was invited to a private group on Zalo and Telegram about the stock market. In the group, there is a person called Mr. Nguyên Văn Cường and assistant Ngân Khánh (the name on Telegram has been changed) who guides some potential stocks. After a short period of time, it was announced to participate in trading on the gold market on the Oanda platform (Oanda-vip.com is introduced as a center affiliated with the Oanda platform for 3–4 years) with a commission of 1%. Then, they enticed members of the private group to open personal accounts, deposit money, and trade according to the instructions of the master. When I deposited $16,000 and traded, I was not informed that I could only withdraw money once, and I needed to upgrade to a VIP account to continue withdrawing. When I upgraded to a VIP account, I was informed that the withdrawal was incorrect, so the account needed to be closed with 50% collateral before it could be reopened. When I contacted them to ask why the two withdrawal transactions were made to two different accounts, there was no response. I hope to resolve this issue to recover my capital.
