I recently had a service appointment at 3:00 for a oil change. I arrive 10 minutes early was checked in by the service manager. I went inside and took a seat to wait for my vehicle to be serviced. I had been waiting for a little over a hour and someone asked me if I was alright. I laughed and told her that I arrived 2:50 for my 3:00 appointment for a oil change and I am still waiting. She stated she will check on it she walked away. About 30 or 40 min later a guy came by and asked if I was here for service I told him yes he asked my name and what service I told him he asked me who checked me in and I told him I wasn't sure it was a guy with the costume with a lot of hair on his head and face he said that was me. He said let me check on it and he walked away. It was after 5 when he returned and he informed me that he was the service manager and that he handed my information to someone else to write up my ticket and and it was not done. He told me that a technician was working on my car now completing my oil change he said he was covering the cost and apologized for the delay. I waited 3 hours with an appointment to go my oil changed. This is not the first nor second time I have waited longer than I should have for a simple oil change. I take my car there for the great price but it's not worth spending half my day there with a scheduled appointment for a oil change
