How do you pick these people that work for you?? I guess the only requirement is that they must be Black, because these people have no idea on how to work with people, They have no personality or skill!! Maybe you should screen them a bit better and check them before you just let them handle your “Guests”
This is racist in the extreme and I think you should modify this part of your original post.
As for putting expensive items in hold luggage, what were you thinking?
I hope this gets resolved to your satisfaction but I would suggest toning it down a bit if/when you contact SAA.
