Oil Change

I was at Jiffy Lube on Satellite Boulevard in Duluth. GA to do a normal oil change and after about 20 minutes into the oil change, I was called to come under the bay to see something. Went in and the man working on my car told me the nut that locks on the pan would leak oil after they finish changing the oil. Apparently he broke it while unscrewing it. I informed him that my car has never leaked oil and I'm wondering why he did this. He told me "well you can fill out a claims form" if you feel badly about this. Filled out a claims form and my horrors began. First they did not fax in my claims form until I called corporate office. Emailed the customer care supervisor pictures of oil leak. Did not get an acknowledgement. They sent one of their staff Chuck who is on their telephone system to give me a call. The horror continued. Chuck was so rude and antagonistic and he clearly was acting out a script designed for Jiffy Lube not taking responsibility for their staff action. Told me the previous company who I have been using since my car was about 10k miles without issues was responsible for the broken nut. My argument is that if their staff knew the nut was hard to remove, he should have called my attention to it before proceeding further instead he called my attention after he got it broken. Now I am stuck between legal action or cough out money that I never planned on spending because I went for a cheaper Groupon powered Oil change.
