The WORST experience of my life. It was the 1st time in all my life that I felt somebody look down on me with contempt. PATRICK MCGARRITY, service advisor, is unprofessional, rude, careless and disrespectful.
On 7/17/2020, I had an appointment to change the glass of my driver seat s window. Patrick gave me the price of the glass by phone but he refused to give me the price of labor. When I arrived to the appointment, I complained about the price, $800 to change a glass, and he responded to me it is what it is . This was completely unprofessional but I did not have another choice than leaving the car there to replace the glass. When I went back to pick up my car, the lady who took my payment told me that the car had other issues but Patrick did not take the time to explain anything to me putting my life on risk. I started the car and before leaving the Mercedes Benz s parking, the car stopped twice. My car was driving without any problem when I left it to replace the window and now, the car was stopping and had a light that said check engine . I went back to the Service office but Patrick was gone already. I drove back to my home very afraid and praying to not have an accident.
After the weekend on 7/20/2020, I drove back to Mercedes Benz to fix the problem. I went to talk with Patrick who acted like he did not care about anything related to me. He then tells me that he did not believe me when I said that my car didn t have any other issues when I came to replace the window. This means he was calling me a liar. I thought that he just had a bad day on the 17th but I realized that this was his real personality. He despised me and he lacks of any customer service. He should not be working in this job dealing with human beings.
