Yes I have, I dropped it off under the understanding that they would investigate and call me to let me know what they found and we could go from there. Nowhere did I say just take the car and do whatever you like and don't call me.
It is not the customers responsibility to call the dealership every hour to chase them down. It is the dealerships accountability to contact the customer and tell them what they found so the customer can make an educated decision based on what they found.
Also, I have called and sent emails requesting that they tell me exactly what they have done. They still have not sent me anything to date telling me what was wrong and what they have done. But they apparently have been doing it for 3 days.
