I came from out of town just to get my car oil changed. I called the automated system says "come in and take advantage of our express oil changing services . you don't have to set up an appointment " So i did that . On google it says they close at 6 . I came in at 3:50. They said they close at 5 so they can't change my oil. Its hard to come by gas right now due hurricanes harvey . (Which I was heading to help out down there.) this is the second bad experience I've had wit this place.
