Unhappy customer

I have been since waiting for vodacom to contact me about this whole mess of a contract I have with them and nothing? These people are the worst ever. The second sim is not working as well and they expecting to pay for a sim swap whereas the sim card was not working from the time I received it. Can these people just cancel this damn contract and come collect their devises as this is not on at all. My whole family and I are porting to a different network as we are very unhappy with Vodacom
