Poor customer service

Just visited cotton on woodmead to pick up an online order. Had a disgusting experience. The tellers are rude, arrogant and speak with utter disrespect. When I requested to speak to the manager I found that he, from the onset had a rude and disrespectful approach. He introduced himself as tumelo or dumelo. When I requested to see his name card which was turned upside down he responded by saying he doesn't have to show me his name card. This was before even explaining our complaint. Upon explaining our complaint he responded by saying that he cannot reprimand the teller. Their attitude and level of customer service is disgusting. The manager himself needs to be properly trained on how to communicate with customers and handle complaints. To me as the customer it seems that this attitude is acceptable at this branch. I will be returning my purchase and until I do not receive a formal apology from both the manager and teller, I will not purchase from either cotton on or Typo again. Being treated as sub human is offensive and I will not tolerate it. By word of mouth and social media I will be sure to share this experience and discourage as many friends and family from buying from these stores.
