O'Reilly Auto Parts

This store just opened a couple of weeks ago and we have bought parts there 4 times so far and every time we get the wrong part! Your employees have no idea what they are doing and have no knowledge of automotive parts at all. They can not help or answer. Questions about parts. I go to O'Reilly stores quite often and the workers are normally very knowledgeable and are very helpful but not at the marlin store! Who ever did the hiring did your company wrong!
