Dis-Chem Tambotie poor Customer interactional skills

I would hereby like to express my utter grief and dissatisfaction with Dis-Chem Tambotie. Today (17:40 the 10th of March 2023) did we hear that my son needs to play a rugby game in the morning. We raced to this Dis-Chem and arrived at 17;50. I sent my son to ensure the Security waits for us as its still before 18:00 (The advertised business hours as per their website. My son was turned a blind-eye as the Security closes the door. This was exactly 17;51. I begged the Security access as we urgently need to get a Gum-Guard for his game in the morning but the Security would not allow us entry. With a very ****y attitude did he sacastically asked what the time is and whilst I showed him its still 7 minutes to the hour did he closed the door in our faces with a smile on his face. Is this how "White" Customers treated at Dis-Chem? Why would the website CLEARLY state 18:00 when its already closed 9 minutes before the hour? I then jumped on the phone calling this branch when I were told that "Due to a high call volume do I need to wait. I held the line till 18:22 while I kept hearing "My call is important to Dis-Chem". Now if they are so adamant to close before the published business hours why would they still take phone calls after 18:00? I was eventually knocked off the line. Now due ti us not able to get a gum-guard are my son not allowed to participate in the rugby match in the morning thanks to this Security's bad attitude.

This makes my blood boil for we are treated like **** even if they know that its not the actual closing minute before the hour. I find this experience pathetic and surely unprofessional. This is NOT acceptable nor even fair but rest assured I will not support this franchise ever again.
