Sim Swap drama

Thank you Vodacom for your absolute **** service. I stood for more than an hour in your store yesterday to get a sim swap done (which was never done) because you said my acc was in arrears. I paid you then and then was told from another agent that it wasn't in arrears and the debit would go off that day. So now I have no money in my acc. The rep said he would call and didn't. He was supposed to help me with the sim swap. I just called to the call centre this morning to find out nothing was processed at all?? SERIOUSLY??
