items added to my bill without authorization

<p>I upgraded my contract with vodacom in february 2017, asking them to change my bundle type as well from small to medium, the agreement was as of 1 march the change over will occur from small to medium. I was asked during the application if I wanted to added insurance and I said no.</p> <p>I then recieved my statement after the upgrade, I was debted for several item that I could not account for such as two bundles both small and medium..etc, I was also debted for insurance not once but twice for one cell phone contract.</p> <p>I contacted the call center to dispute my invoice statement. They agreed that my dispute was valid and I would recieve a refund with 7-14 working days... </p> <p>I am very disappointed with the service from vodacom and find it difficult to understand</p> <p>1) How is it possible to debt my account for an insurance that was not authorized by me. </p> <p>2) Why was I not contacted first when the so called mistake occured.</p> <p>3) why are there no procedure in place to ensure accuracy with regards to our invoice statement matching the actually contract that I physically signed and my itemized billing.</p> <p>4) Why was I not contacted by vodacom after the issue was logged.Almost two months has past and still nothing not even a courtesy call or any feedback whatsoever.</p> <p>5)This really concerns me is this the first time? or is it the first time I actually took note of it.</p> <p>I have been more than patient and would like to know whats going on???</p>
