Vodacom Centurion Mall bad attitude

My husband and I went to do an upgrade at Centurion mall … we both sat next to the sales consultant that was assisting us ( I don’t remember her name but she had good customer service) however her colleague who’s name is Pat showed up and shouted at me out of the blue ( I believe she was telling me to move from the chair in a language that I did not understand . so I spoke to her in English and I told her I do not understand what she was saying and she continued shouting at me .. we ended up leaving before we could continue with the upgrade as we were both furious… so the sales consultant that was assisting us followed us as we were about to leave the mall and apologised on Pats behalf and told us that’s how she normally is and we should pay no attention to her which was obviously impossible to do because were paying for the service. So we eventually went back to the store to continue with the upgrade I was so shocked to discover that the store had a manager because of the bad attitude we experienced there. Kudos to the sales consultant who did damage control I hope the manager can learn a thing or two from her.
