Charging me twice for the same product

In June 2015 i was contacted to upgrade my Paint and Scratch insurance as there were more benefits and more extensive cover I would receive. I was told that I would on need to pay a total of R99 per month, as the increase was minimal from my existing cover I was fine to upgrade.<br> I understood that I would be charged both my new premium and existing premium in July 2015 in order to avoid a lapse in cover but then i would only be charged the R99.00 per month.<br> It is now November 2015 and I am still being charged for both policies.<br> I have contacted the Customer Care centre and all they can add is that they agree that I should only be charged the R99 and not both amounts.<br> I am sure that this is not only ********* but highly ******* to continuously charge someone for something twice.<br>
