Denied Claim

I put a claim in August of 2018 for my radio on my Hyundai Genesis I made the mistake of telling them that I would be out of town for at least 8 months working and that I drive my car. Well they didn't do anything for me before I left for work so when I got back I tried getting my car fixed and they told me that my car was 200 miles over my warranty even though on my original claim it shows that my car was 15,000 miles under when I submitted my claim. They were really disrespectful and I wouldn't advise anyone to use them and if I could I would start a law suit against them.
