Falsely accused of theft at Pick n Pay

Yesterday the 28th of September 2020 I went shopping at Pick n Pay Sunbel Park opposite Sanlam Hof. I took to roll on's off the shelves and was looking for some deworming medication in the baby's department. After not getting what I went there for I left everything as is. I've put the roll on back on the shelves and when I was about to exit the store. The security stopped me and said that someone saw me taking 2 cans of spray and he needed to search me he continued by doing so in front of the whole store by the exit and had unpacked my whole work bag taking out all my lunch boxes, my Laptop and other personal belongings. After not getting any of those items I was accused for, he insisted that I took him back to where I put the spray. I told him that I haven't taken any spray I only took 2 roll on's after I showed where I've put it. He let it be and let me walk without an apology of some sort. I am going to take legal action against this matter as my work place is right across Pick n Pay and I now have to prove my innocence at work since one of my colleuges saw the incident and reported it to my management.
