Vodacom online extremely rude staff member

I had the misfortune of dealing with Sean Jacobs of Vodacom online on 19 Feb 19 when he phoned me with regard to my online contract application I had made on 17 Feb 19. He could not answer my question regarding my previous contract with Vodacom and proceeded to get extremely rude and sarcastic with me when I asked him for further details, telling me that I must phone the customer care number if I wanted an answer. I asked for his manager's name as I wanted to report his conduct. He again told me to phone the customer care line if I wanted his manager's name, and then had the audacity to put the phone down on me. I have been a customer of Vodacom's since 1999 - 16 years on contract and the last 4 on prepaid. I don't expect to be treated like this when I am asking a legitimate question.
