Terrible Service Department

Such terrible service. Unable to find the electrical fault in my car, blamed the tracker and told me to take it out. Removed tracker and then nothing changed, I attempted to get hold of someone at Audi, no one returns your call. Went down to the dealership to get assistance and all I got was a bad attitude, passing the buck. I am done with Audi after many years. Just ******* service and ******* cars.
