Disgusting behavior of Food *****s staff and management

I am totally disgusted at the behavior of your staff at Food *****s Market, Newspaper house, 122 St Georges Mall, Cape Town City Centre, Cape Town, 8000. On Thursday 1st April 2021 at 2pm I visited the store with a group co-workers. We purchased our meals and decided to have a sit down in the lunch area just outside the exit of the store. The four of us finished up and on the way out I stopped at the bins to dispose of containers. As we walked to the exit I was stopped by one of your employees and was asked where my slip was? I had already thrown the slip in the bin at this time and this is exactly what I told him. I then asked why had he stopped me out of all the people in the food court? He couldn’t answer me, instead he asked which way I exited the store?? Why would your employee ignore a perfectly relevant question and not answer me? I then asked him what exactly he was asking me, because out of all the people in here he stopped me (A coloured male with tattoos)and asked where my slip was? I repeated my question asking why is he asking me this, in front of all the other people, creating a massive embarrassment for myself, (I am a Operations manager for one of the biggest BPO’s in SA), He still couldn’t answer my question. I then asked for his name and for him to get the manager. He refused both requests and said he couldn’t leave his post. Which is strange because he stopped me nowhere near where he was supposed to be. I then requested the manager again and he refused, instead telling me to go to the offices myself!!! Excuse me?!? I am an upstanding, honest, well respected member of the community and your staff is treating me like a piece of dirt!!! The manager must have heard the commotion as he came rushing out to speak to me. I explained the story and he apologized and then mentioned he would need to check the video footage!!!! What the actual Hell (Replace that with the expletive of your choice). Check the footage? Yet again this made me feel like this has more to do with the way I look than anything else. I asked for his name, which he refused, and the email address I could lodge my complaint to. He refused this as well saying we should go to his office, I obviously refused this as your staff chose to embarrass me out in public and now they wanted to deal with a racial complaint in private? I am sorry this is not going to happen. I will not stand for this type of behavior from anyone. I requested the email one more time which he refused again, I asked what kind of a manager doesn’t know what the email address is of your head office or complaints department. I quickly realized that this was going nowhere and I took a video with a brief explanation of what I had just experienced and I have the manager's face on camera, please feel free to request this footage. The level of anger and embarrassment I am currently feeling right now cannot be conveyed in words in an email. I expect to be contacted within the next 24 hours with and sincere apology from a senior member of management of your company and a resolution to my complaint, as mentioned I am a Operations Manager in Customer Service so please make sure whoever contacts me has all their ducks in a row, or I will take this complaint of blatant ****** public on all social media platforms.
