We're very disappointed that you haven't been satisfied with the service our team has provided on your vehicle. We certainly hold our service department to a high standard, so this is upsetting feedback to receive. I understand you plan on taking your business elsewhere, but if there's anything I can do to change your mind, I would be more than willing to assist. Please give us a call! Thank you
