Question
My insurance company has been insuring the wrong car for 3 years
Answer
If you have proof that the car was supposed to be changed three years ago, you should be able to get some kind of compensation. Ultimately, it is up to the insurance company on how they handle billing and policy disputes. You will need to contact your insurance company directly for your policy specific information. If you do not agree with what they say you can always seek legal advice. Good luck and if you have any questions, don't hesitate to ask.
