Walmart Auto Care Centers

this place doesn't have their hours on any website, so i called before making the ten mile trip to their store and they told me as long as i came before 7 pm i could get my oil changed. got there at 6:30 and they turned me away saying they can't do an oil change in twenty minutes. they were no help when i explained being misinformed and didn't even reprimand whoever gave me false information.
