no customer service after making payment

I’ve had a poor experience with my recent purchase. First, I was **** to about the service history, which I found was non-existent after taking delivery. Second, I discovered a missing locknut and a stripped wheel hub. The dealership’s claim that it was 'safe to drive with missing bolts' is unacceptable. Because I couldn't risk a week of downtime or my personal safety, I paid an independent mechanic to fix the hub properly.
