safety

How safe it is to do shopping at Westgate with all the security around you but when you require assistance their camera's all of a sudden are not working, I went to do shopping on the 27 March as I entered Truworths my phone was taken out of my pocket and I told security at Truworths and they told me they don't have camera went to the centre management where I was advised that their cameras are not working. The question is how safe is a person doing shopping at Westgate Mall Roodepoort is? We could have found that person if all the securities came to the party. Is it safe at Westgate Mall?
