Luggage rummaged through, valuable item taken

I flew from Kimberley to Cape Town. At the baggage claim in Cape Town I immediately opened my luggage to be sure I collected the correct bag. I was disappointed to notice that someone had been through my bag, with items removed from their containers and everything left in a big mess. Unfortunately, one valuable item was removed from the bag. I complained at the Airlink office in the domestic arrivals area where they apologized and explained that luggage handling is outsourced, and said that I would not be compensated.
