SIM not working

<p>Since Thursday, 15 September 2016, my SIM card stopped working. I have phoned Vodacom on the following Friday, where they have synced the network. It did not work. On the following Saturday, I visited a Vodacom where they took my details in order to sync the network again. It did not work. They told me to swap my SIM with another phone in order to determine whether the SIM or phone is faulty. The SIM card did not work another phone, so I did a SIM swap on Monday. The SIM swap did not work, so I phoned Vodacom again today where they synced the network again. It did not work.</p> <p> </p> <p>I need this sorted ASAP, as I am unable to access the Internet or make and receive phone calls. </p>
