iPhone doesn't work, no support from Vodacom

<p>I initiated a new contract end of May. Received iPhone 7...first week the microphone is intermittent in its ability to function leading to much frustration. I've done two resets, same issue persists. Your call centre says I must send the phone in, they'll cancel the contract and I'll need to initiate a new contract...which took a month previously as per my only other Hello Peter post. I now have a non-functioning iPhone 7, a poor perception of Vodacom and a pending contract with Cell C because of your incompotence and inability to manage an otherwise simple process. I want my contract, I want a new phone...simple. I dont want to have to go back six weeks in my life because that's "how the system works". Fix it. </p>
