wrongfully accused

This morning when I want to pick n pay to buy as I normally do on a daily basis, the security lady that works there stopped me on my way out of the shop and she told me to go back inside the store she wants to search me, she called one of her male colleague's to search me. they took me to a room where they asked me to take out everything in my bag they even asked me to take off my trousers then when they couldn't find anything I asked them what now as they have violated my rights they called the store manager who was rude and he never introduced himself he just said hi I'm the manager I apologies their just doing their Job then he just walked. I left the store embarrassed as I was the topic of conversation and too make matters worse this has a affected my reputation as I also work in the mall im now called by names. Pick n pay has to fix this mess
