I'll cancel it. The clerk also made many excuses not to let me cancel.
Finally found an embarrassing reason. Let me transfer all the funds in my account (I only had a penny in my account at that time). He said he would solve the interest problem for me. Let me cancel the next day. Use delaying tactics. But it's done.
Actually, it's not impossible to cancel. General securities companies have regulations. Now that I'm here, I won't let you leave easily. Because only your account exists can you trade. They can make money by trading. So the salesperson canceled you. It may involve things like deducting bonuses.
You can take your documents with you and make sure they are complete. ID card, shareholder card, capital card, etc. Go to their counter during business hours and tell them: there is no reason why you have to cancel. You don't need anyone's signature, just as you can open an account without anyone's signature when you open an account. As long as you agree. If they still find various reasons not to do it for you, you can tell him. If they don't do it, I'll complain to the China Securities Association or the CSRC. It'll be ready in a minute. Easier than opening an account.
