Car Dealership Ruined My CD Player. What should I do?

I brought my car to a Honda dealership for maintenance and asked them to look at why my aux port didn't work in my car. My parents bought the car used several months ago so it had some warranty on it. Anyways, they found a chip in the port, replaced it and discovered that wasn't the issue. I wasn't charged for it since they didn't fix the problem, but they told me I had to get a new radio because there were coins inside it. They tried removing maybe 50 cents worth but I now notice my cd player doesn't work at all. I asked them to fix the problem, was ready to pay until the costs entirely changed from $130 to $450 for a new radio. I was more content with at least being able to listen to cds but now I can't. What do I do if anything?

Try to find a solid case or be able to prove it sometimes if you tell them your story they will do it for free. With my experience with my dad sometimes if you raise your voice a tad it helps other times it dosnt and makes the matter worse.
