Bad customer service from Dis-Chem Sasolburg

On the 28th of March 2024 we experienced bad customer service from one of the cashiers, Zandile Maseko, from Dischem Sasolburg. Who made it look like my grandmother was a *****, and made her wait for over 1 hour with the security guards and caused her trauma. She didn’t care to explain what was happening and just assumed the worst that she didn’t pay for the medication she came to buy, even though she had proof in the form of a slip. Zandile showed unprofessionalism and showed no empathy or remorse, including the manger. Because we reported the incident to the manager who said she will investigate the matter and revert back but to this day she hasn’t gotten back to us. I don’t know if it’s because she’s a pensioner and she’s black.
