Poor customer care and Business ethics

C&J Automotive Stikland don't deserve a star at all. I went there to buy 1 rocker, 1 balance pin and two bushes. The sales man made a mistake while I'm still on their counter and billed me two balance pins. He couldn't credit me on the second pin and on top of that he supp**** me with a wrong rocker and no refund either. I ended up buying a rocker some where else. Whoever out there looking for Automotive parts, please don't consider C&J Automotive Stikland it is like a *****ing business
