Agent behavior.

I called in on the 14th of November and spoke to an agent by the name of Thobeka Hlongwane who works Telkom Mobile in Durban. The agent was very rude and sarcastic towards me. As a customer if I'm calling in to seek assistance due whatever situation I'm in, I'm expected to be helped, yes I will somehow speak out of frustration for certain reasons which I do not mind being corrected for if I'm at fault.... But if you become sarcastic towards me and rude then it's a different case. I did not appreciate the tone and level or sarcasm this agent used towards me and I'd hope she gets trained further on how to deal with frustrated customer.
