Flysafair staff are dishonorable

I have used flysafair atleast three times in the last 5 months. Every time their staff break open my luggagae and damage my bag. I had to complain this time. When i spoke to the pweson at the baggage area after getting my luggage from the carousel he advised me not to lock my bag, whether wuth a cable tie or a lock. Because it means i have something precious inside and thats why the team wants to open the bag. Thats ridiculous. Teach your staff respect for peoples possessions
