No sense of owning a problem

I purchased a piece of art from a small art gallery in Koblenz Germany. The gallery sent my parcel by DHL and supp**** a tracking number and the German web site link. I was able to track the parcel until it arrived in SA. Now I cannot track the parcel and not one person that I spoke to at DHL SA wants to or can assist me. I must the employees I spoke to were friendly but really very good at passing the buck. Even said I should contact the art gallery - how cool and helpful that is. Useless company
