What if the insurance company deducts the premium without my knowledge? No business relationship

I don't renew your fee privately, but remit it automatically when it expires, which has nothing to do with the salesman. The salesman also has no authority to operate your account.

Life insurance companies are like this now.

It's not that you don't know, but that the insurance agent didn't tell you clearly when selling insurance to you!

The only thing you can do now is to ask the salesman (if he doesn't do it, he will renew the order, and some companies also call it the customer service department) to ask for your renewal order!
