In May 2021, I was recommended by netizens to deposit funds in Zhongyuan Finance. After trading for a period of time, my account was worth 3w yuan. When I withdrew the funds, I found that they had been frozen, claiming to be a high-risk account. The funds had already been frozen... So I asked customer service for the reason, and they gave me a QQ to add, claiming to be my exclusive customer service. In fact, I was also puzzled, At that time, I filled in the bank card number word by word against my bank card. Later, I checked it twice and confirmed it was correct before submitting it. After the funds were frozen, I realized that a number had been filled in incorrectly. The customer service said it was because of my own mistake that I had to pay a certification fee of 12000 yuan in order to unfreeze
