What you reflect is that tying insurance products with loans is definitely illegal. I suggest you take the following measures:

First of all, go to the bank to communicate the situation and clearly tell the bank that you don't need insurance products. At this time, you can hint that you are going to complain to the insurance supervision department. In the meantime, you should collect evidence of rights protection, and it is best to quietly record or collect other written evidence.

The second is to complain to the local banking supervision department by telephone or the Internet, and the banking supervision department is generally located at the provincial level.

I hope my answer can help you successfully defend your rights. If you are not sure, you can consult in the station. Good luck.
