Worst service at PostNet Krugersdorp

Sent my parcel through DHL at PostNet Krugersdorp and they purposely opened one of my herbal product. Had to drive 6 km to fetch a replacement and they receiver told me they opened the same product again after I left. Will never use them ever again. I wont usePostNet Krugersdorp ever again, will rather go straight to DHL head office Peter Place.
