Credit car insurance

Good afternoon. I ask you to help me with this question: I have a car on credit at the bank \"Nadra\". It's time for the next insurance. The bank requires insuring the car with insurance companies that are accredited by them. (In the contract, this literally sounds like: \"On the day of concluding this contract, insure the collateral with an insurance company that is on the list of those accredited by the bank\"). I am not satisfied with the quality of services provided and the cost. I want to insure the car with another company that is not accredited by the bank. What could this threaten me with? Thank you.
