Came for an oil change about a month or two ago. When I came everything was good until I heard a noise from a.c. So I looked under my hood. Noticed a cap off. Around it was debris and tree falling. So I put the cap back on until my next change to point out the problem. Cap was still on. So I said it had to be a problem they caused. Now I am here and they're trying to charge me $80 for diagnostic. $400 for part. I have the number for NAC. Part replacement. But I feel I shouldn't have to pay for anything I didn't cause. They left off my cap messing up my blower motor. Which I feel isn't even messed just filled with debris. My car is basically brand new. I feel this was malicious. I want to go to another autonation because I feel this one can further sabotage my car. I have 3 more oil changes. I would like to see if I can get a refund.
