I took my car to a shop for ac work, they had it for a full week. I went to the gas station right after and I noticed scratches on my trunk. I poured water on it to make sure my eyes weren’t deceiving me. I called them and told them about it. There is obviously grease on it and I know I didn’t take it in with grease. (They said they will ask the other mechanic because they no nothing about it.) Any advice?(edit: the car had minor scratches but nothing that big and car was stored outside while repairs, I live in a really dusty area)
