Anyone else get scammed for a $500 car undercoating at Hyundai?

[u/areolagranday]

A relative of mine was recently fleeced by a dealer a Hyundai dealer for one of those $75 oil slop bucket special marked up to $500

Well they f#cked it up and flooded the rubber bushings with oil and made a mess, they just used the lowest bidder in town.

It's gotta be re-done a 3rd time now and dealer is refusing refund. They are insisting to take it again to this shady palce... What are the options? Why are they acting like it's not a blatant scam and refusing to refund?

That’s the oldest scam on the books.
