Pick n Pay Towers Boksburg Harassment

On 15 sep 2018 i was shopping ,as i usually do at Pick n Pay Towers in Boksburg .I have been shopping there for the last 3 odd years. I was approached by a manager called Frans Kruger and was told i look suspicious.I left the matter ,as i know i had done nothing wrong. One week later ,Frans Kruger told a security guard to watch me and so he watched me the entire time i was shopping. I complained to another manager but nothing was done about this matter. Frans Kruger does not recognize me after 3 years of shopping there daily ,but can spot so called "suspicious behavior". This begs the question as to how he even got the job in the first place, because i have never met a manager with so little tact and manners. It seems like i will have to shop elsewhere as this is not going to end. This is blatant harassment in my opinion, or is Frans just trying to prove something?
