Pathetic Service from Foschini Group call centre

Apathetic service from a call centre agent, by the name of Aphiwe or Aviwe, she was calling me regarding my Markham account, but I was struggling to here the agent, when I asked her to repeat what she was saying, she got irritated and spoke in Xhosa in a very rude manner, I asked her that, can I be called by another agent, she insisted on explaining herself, I told her that, I need to speak to another agent then hanged up. Guess what? I have been waiting for their call, boom I receive an SMS today that, they have attempted to call me, when I never even received any call from them since yesterday, how pathetic is this.
