Being sent from pillar to post

My phone does not receive call and smses so I called the call centre 111 three times and each time I get a different response. The one agent promised to log a call and someone will get back to me within 24 hours but I am still waiting for that call even after 24 hours. I had to call back to give my alternate number as the agent did not ask for it even after I told them my phone does not receive calls Today I called and the person I spoke to say I must do a sim swop. I am really frustrated as I am not receiving any calls and this is the line I use for business. The number I need help with is *** but my alternate number is ***<br> <br> I would really like to get a definite answer from vodacom in this regard.
