Jet store Wynberg!!!! Assaulted by security

I went to Jet store in wynberg on 22nd April I was in there for literally 30seconds to browse for a birthday gift for my mom. As I approached the door the lady security asked if she could check my handbag, I rep**** no and said I have nothing in here that belongs to you. She said I'm older than you, you must respect me open your handbag, I said no and walked, she than grabbed me by my arm and pulled me into store and said open your handbag, I said I'm not going to open it because, it's a different thing if I had bags on me but this is my personal handbag. She then said she won't let me leave the store until I do so. By this Time there were so many people standing infront watching what's happening and as I approached the door she pulled me on my left on and a male security pull me on my other arm very aggressively . They then called the manager and the manager said that it's their job. I responded by saying where does it show in this shop that we need to open our handbag when we leave. A lady from specsavers then said to the manager this is assault how they grabbing this young lady and he (Manager) then said I will speak to them sorry about this and said I could go, I said he can look in my bag to show him that he literally treated me like a ***** and embarrassed me so much infront of all these people to only find no belongs of them inside. I am utterly disgusted and in shock with how this was handled. I did not touch anyone of them. I have a ugly bruise on my arm of how I was handled by them. I cannot believe I was treated like a ********. I honestly truly believe these things should not go unnoticed.
