Disgusting service

I am writing this because I am very disappointed. On the 30th of June, I called and spoke to the first lady, who was very rude and impatient with me. I was trying to explain the nature of my call; she was so in a hurry to just hang up the call. How do you employ someone in customer service who fails to service the client? If it wasn't about us as clients that she needed to service, she wasn't going to have that job that she is failing to do. I was very angry because she even just put that phone away so that she wouldn't hear me speaking. I ended up hanging up the call because I was talking alone. I called again and spoke to Nqobile Nkomonde, who I still think is the same consultant I was speaking to because the behavior was the same: she was shouting at me and talking on top of me; she was so irritated to assist me. My question is how the employer employed such people. Were they trained, and also do they know their job distribution, these ladies?
