Traumatic experience by my son from clicks staff

Good day Clicks management. I write this post here with great anger and frustration over the treatment we received from your store today(21/09/2020) at Clicks Sterkspruit (Eastern Cape). I sent my child to buy two bandages and gave him R25, he got to the till to realize that the money is not enough and called me. I advise that he buy one instead, and he did. The teller for some reason puts the second bandage inside the bag and my child leaves the store only to be stopped by the security guard, who despite his(my child) explanation, calls him a *****, threatening him saying that he must pay for the other bandage. My child was held hostage(for more than 15 minutes) in public and embarrassed for your mistake. I had to rush to the clicks store to rescue my child. I found him there with the security guard and the "manager". I ask why my child is held hostage, I hear mumbles and I called the teller to explain and he agreed to his mistake and that's when we left. It is really sickening to have clicks put their shop to service our people but all what you see in us is *******. Had I not arrived, what would have happened to my child? He is to this time still traumatized by the treatment he received. This is sickening, unprofessional and ********* to the human race!!!!!!
