unprofessional management and poor infection control

I am extremely disgusted and appalled by pick n pay mall la Lucia. As the management have bad attitude and the kiosk staff do not have the decency to explain what a terminology is they think you are doing them a favour. ...they will actually come to your work place and harass you although you was a customer at pick n pay I strongly advise you not to shop there. the assistant manager will harass you at your place of work and bring security to intimidate for no reason it is disgusting that people do not have any knowledge about the law and he kept insisting that he gonna bring the police to arrest me for merely complaining about bad service from his staff . My national brand manager also advised him that this has nothing to do with the company I work for as I came in as a customer....... And if he has issues he must deal with it out of her company. I am very knowledgeable about the law and do know that no one can arrest me on a sunday without a case being opened and being found guilty in the court of law also under what grounds ....so it clearly shows that people want to be assistant managers and think they are in this post that they can bully people. I do have a part time job and I do have a degree and also studying law . he literally harassed me in my place of work........my question is how can a manager be a manager with no general knowledge about the law but he starts screaming
