Bad Attitude on a call they made to me.

Good day <br> <br> For the last two weeks I keep getting a call from a withheld number. Yesterday I decided to pick up the phone. The man on the other side took so long to say why he was calling. I could not here where he was calling from but he did say its on behalf of Vodacom. I then asked if its in connection with a new phone or tablet. He said yes its about a new tablet for R76 a month. I then confirmed that I really, really don't need and cant afford another tablet as I already have two at home. He then asked me why I have two tablets at home as I should only have one. I did confirm that it has nothing to do with him and he then asked me what type of tablets it was and again I said its personal. He kept on going and I then said, thank you very much but not thanks and said goodbye as I was busy with a class. He phoned me back and told me that I was rude and that I don't need more than one tablet - I wanted to talk to his manager and he said that he is the one talking to me - he did not want to give me his name or the place he was calling from. He was getting really personal and yes I got upset when he called my back and said I was not telling him the truth that I was busy.
