I cancelled my service because of a person named Richard who was extremely rude to me when I called about my last delivery. He was in the office. I called back a little later hoping to get someone with manners but got him again and then just told him to cancell my service. On the first call I asked him to have a manager call me back. Well that took over a week but a manager did call back and was very nice. She did a review on my oil useage but never apologized for the rudeness of Richard and never asked me to stay with Trevis.
