Character Defamed

On Tuesday 26 September 2023 I went to Ultra Liquors at Goodwood Mall. As we had many packets my wife stands outside with the packets. I proceed inside the shop with a packet of chips from Clicks. 5 minutes later a security guard comes running after me and shouts to me saying that I better put the chips away. I look at him thinking "You don't have to shout at a person". A customer walking past starts laughing and I was seriously put in the eyes having my character defamed. After purchasing the gift I proceed to speak to a girl sitting in-front of the checkout section and I then ask for the store manager, only to be told that the manager is to busy to speak to customers. I proceed outside and then rather go straight to the security guard to provide constructive criticism and then advise him that in future he should rather be standing by the door and to inform customers at the door that they should not go into the shops with chips. After providing the security guard with this information with the constructive criticism I hear another employee shout "But they did call you". I then tell him no they did not and my wife then comes closer and also states that she was standing by the door and nobody called me. The Ultra Liquor representative again shouts at me stating once again "Not but they did call after you", Very Rudely if I might add as if he were talking to a minor he does not respect. My wife then states that the security guard and him were standing on the far side of the entrance talking about their weekend. At this point I then go back into the store and insist that I need to speak to the Store Manager right away. I am then showed to the store manager who was in the store. I advise the store manager of what happened and she just looks at me. No "I am sorry about that sir" Or "I will address the issue and make sure that this not happen again in the future". The store manager then goes outside to speak to the employee and as I'm walking away the employee says "No this customer is mal". So now for the 2nd time I have my named defamed in a short visit at Ultra Liquors. The manager does not say "You should not speak to customers like that" or "You should be respectable to customers. The only thing the manager says is "You must come to me if you have a problem with a customer". She did not even tell him that he should not speak to customers like he wants or that he should not call customers "mal" or more importantly please make sure in future not to defame the character of customers. Proving that bad management leads to bad employees. Head Office should really go and see how this specific store is being run as I'm pretty sure defaming the character of customers is not the Ultra Liquors manual.
