Victimization! - Consumer Complaint for PEP STORES

I bought some items at pep in Parklands a few weeks ago and when I wanted to exit the shop the Security asked me to open my personal handbag. I then requested to speak to the manager. A lady named Faeza then came and started arguing as to why I don't want to open my bag.I wanted to leave but she then grabbed my arm and refused that I leave the shop.This is what I would call assault! I was so embarrassed and stoked at this behaviour. For weeks now I'm in between whether I should lay charges or not.
