Fidelity service such a shame

We went to buy food at the N17 petrol station. There was one of their bakkies as my husband went out to put the cool drink in the car the Fidelity service was parked out side. He asked the guy if he can pass because they were not busy handeling money or even looked if they were working. The guy swore at my husband so he walked around the bakkie. Upon his return the guy grabed him by the arm so my husband told him to not touch him and preceeded to enter back in. As the guy followed and started to assualt my husband. I got in the middle of the fight and told the guy to leave. I took a photo of the reg nr and they just got in the bakkie and drove off. Only for my husband to relise that the wallet in his pocket is missing. For a security company i can not believe what happend it is a shame to know they let such people work for them.
