Yes, you should be reimbursed if you were actively insured during that time. I would call the carrier you had and make sure the lien info is listed correctly, and then obtain all declarations and a letter of experience. Take that to the loan/financing company and they should reimburse you on all the insurance charges. As long as you were in compliance with your loan terms, they can not force-place coverage.
If you have any other questions, don't hesitate to ask
