Expensive item ****** from suitcase on Airlink flight

Was very surprised with Airlink ground staff at OR Tambo when getting my boarding pass, they did not greet or smile. I also had a small suitcase and asked if I would be allowed to take with me on the flight, the lady asked if I had any liquids bigger than 100ml to which I rep**** that I did have a large perfume so gave my bag in. When I reached Dar es Salaam I noticed my zip was slightly open but didn’t think much of it as when I opened it at the airport all seemed in order. However on reaching the hotel I saw that my perfume was missing from my toiletry bag. Will not fly with Airlink any more, after paying a premium price for a bad experience.
