Big O Tires review: Oil change service

Twice I called for an appointment for an bbn oil change and both times they said come in on a monday at 3pm. The first time they rescheduled me because they had no record of me calling and they were busy. The second time the manager ed came out and asked me what I needed obviously I was not on record again. I told him and he rolled his eyes and said oh god... There was no parking to boot. I walked out and will never go back. He came to my car as i'm waiting at the red light to leave tapping on my window. I'm ready now he says. I would never feel as if they did a good job considering they were so busy. I don't appreciate my slot for service being unrecorded and unsaved. Not once but twice. His attitude was atrocious... Thank you...
