I feel like im getting ripped off

Z RATED OKC

A couple weeks back my a/c goes out so I take it to the dealership to get it fixed I ended up spending like $200 by the time I got back the a/c stopped working an all the a/c fluid leaked out which was odd because they performed a leak test, last Friday I decided to take it back because I also needed a oil change now they are wanting to charge me $500 because they claim since my aftermarket CAI it rubs on the line causing it to leak this just seems like a load of bs and I've already paid them once to fix it
