Dealership Problem

Update:

We had my daughters car checked by another Dodge dealer. They took 3 hours to look over the car in general and all the repair orders in the system.

It turns out that her Dart has the 1.4 L Turbo engine that takes synthetic oil. The faulty dealership has been using regular oil for the oil changes.

The good dealership today drained the engine, changed the filter and filled it up with synthetic. They feel there is no damage to the engine.

The Kicker:
After finding this out my daughter posted to Facebook a simple post that the faulty dealership had been doing the oil changes too often and using the wrong oil. I saw the post and it wasn't rude or vulgar, only a matter of fact statement. It got back to the faulty mechanic who performed the work who responded on Facebook by calling her a stupid C word.

She simply took a photo of the top of the engine where it clearly states "Synthetic Oil Only", posted it with the caption, "if I'm so stupid can you tell me what this says?"

I will never recommend this dealership to anyone ever again.
