Full Conversation

I went to an auto parts store to get a new battery, but they put it in backwards and fried my car. They took my car to fix it at the car shop they preferred, because they told me they'd take care of it. They had the car for about 20 days. A few days after I got my car back they want me to sign a release, but they won't send it to me to look over first.
