Very Bad Service

The service I received at Fury Fourways was distasteful. Shadrack Mokopane - the consultant working at The Service/Genuine parts department had no customer service what so-ever. How do you sell "genuine parts" with no proper packaging? And what guarantee do I have that the part (oil drain plug) is not damaged or removed from another vehicle and sold to me? When I requested packaging from the consultant, he continued to give me attitude and gave me some plastic with the label "Bolt kit propshaft". This is the second incident with this dealership.
