Terrible and disrespectful customer service

Lebogang, the cashier at Waverly Plaza Ackermans was extremely rude. Allowed custmers who left the que to be assisted before myself who was waiting in the que and then CLEARLY spoke about me with said custoner in her language and laughing. When speaking to a manager afterward about the incident the cashier refused to speak English to discuss the matter and gave attitude to both the customer and the manager. The manager, Elizabeth was unable to maintain her staff and to show any authority. The cashier is clearly of the opinion that she is in charge of everyone in that shop.
