Arrogant and Very RUDE

What a disgusting service I received from one of the consultant by the name of Ndivhu. I was querying my statement number *** as to why the money is more this month, she simply told me that the amount includes vat and that is the same vat i pay at Shoprite , pick n pay and etc. I then requested the amount of vat on MiAssit she told me I must calculate it and as i was trying to talk girl went on and I told her she rude because she didn't want to listen to what I was asking she then put the phone down on my ear. Is that how Cell C agents treat their paying customer? The girl was VERY VERY rude she did not even put me through to customer survey to rate her service. She put the phone down on my ear
