Bad Service from an Customer Service Agent at CELL C

I made a phone call Cell C Customer service who transferred me to another department. I then spoke to an agent by the name of Dieketseng Mashaewane. She was very rude and condescending, I was trying to ask her something when she told me to be quiet so that she could talk????? He response was not related to my query. I received a response from the Written Correspondence Dep stating "We would like to apologise for the service that you received". It appears to be a standard response. I then sent an email stating that I was not happy with response and that I wanted to know if the lady had been addressed about her behaviour. She clearly does not have people and has not business in dealing with clients. I want to know that the matter was addressed her and what action was taken. They sent me an email to state that they had tried to get hold of me and that I needed to confirm that they have the right number. Which I did. It has been 2 weeks and I have not had a response from the. Disappointing!!!
