I regret financing my vehicle with standard bank

Standard bank I nonsense I regret financing my car with them. Now they insure my car with Holland and I have my insurance. I did send them the proof of insurance. Since I pay the vehicle on time now they want the commission with insurance. How can you take insurance without consultation and confirmation? I want that debt of insurance to be cleared I know you don't take clients serious. Guys don't do loan or vehicle finance with standard you will regret. They have rude employees
