OKX platform suspected of colluding with currency dealers to defraud money. On December 2nd, I used the payment method of the currency dealer in C2C to transfer Canadian dollars according to the address. The currency dealer insisted that they did not receive it and refused to make the payment. I complained to the platform, and the platform asked me to provide information. After I provided it as instructed by the platform, I have not received any response. Today, on December 14th, the platform directly canceled my order. I did not receive the purchased USDT on OKX, and my bank account has not been refunded. I complained to the customer service, but they just referred me back to the so-called specialist for investigation. I sincerely advise to be more cautious when trading on OKX. I will not use this platform anymore because the risk is too high.
