Insurance company overcharged me for 5yrs on my homeowners ins - do I have any rights in requesting any money back?

Question Details: During renewal of my policy & wanting to know why they wanted to up my policy by 5 grand. I found that they had the wrong info on my home. They had my home as a 1 1/2 story house with a 1 1/2 bath with a full finished bsmnt etc...with being insured for replacement value. I told them that I only have an 836 sq. foot Ranch home with 1 bath & no finished bsmnt. I inquired that since they were over charging me for a bigger home for the last (5) yrs was I due any type of refund and they said no. Important Notice
