Disgusting attitude from a Zimkhitha at the customer service who didn't want to give me her surname

I call in to the vodacom customer service contact center requiring feedback for my refund that I asked for on the 2nd. My call goes through to a Xhosa-English speaking consultant named Zimkhitha who at the end of the call refused to provide her surname. Tells me that I'm not the only client of vodacom and "the back office" is still busy with it and she doesn't know the turn around time and I must just be patient and goes on to give me unnecessary information that I didn't ask for and even fails to give me the information I require. I'm utterly disgusted by her attitude and level of professionalism I'm not her friend and don't want to be spoken to as such. If employees are not happy about their job they mustn't take it out on us clients. This could have been easily handled with saying I'm not sure how it's gonna take but I can assure our back office is busy and will attend to your query not the utter irrelevant nonsense she was telling me.
