Swearing Vodacom Manager

I am a 67 year old client of Vodacom of ten years standing. I went to the Vodacom franchise in Pinelands Cape Town to buy a phone today. After I was sold the wrong phone I asked for the sale to be cancelled. The manager began shouting at me. He used foul language and when a young man tried to intercede on my behalf, the manager told him to "f....off out of my shop." He told me that the very helpful and charming young sales person would "have to pay for the f..... phone" Eventually he did reverse the sale saying he "didn't have time for this sh..." . I was shocked at the behaviour of this out of control diva. ...truely shocking. I expect a response from Vodacom and the franchise holder.
