Over charged by Vodacom

I have received an astronomical cell phone bill of R7635.30. Where my average monthly bill is R2500. <br> <br> An amount of R4826.14 was charged extra for the month of December.<br> When I went to Vodacom store Pinetown, They told me that there is nothing they can do.<br> <br> The charges were for some sort of registration that I have never done , nor have I given any company , app or anything or anyone my consent. Not to mention I have never received any SMS to notify me of any extra charges to my account or to even let me know what it is im registered to ???<br> <br> As a loyal customer to Vodacom for over 14years, I would expect some sort of notification .<br> <br> As the customer, I think it only fair that Vodacom pay me back the R4826.14 as I have received nothing for it.<br> <br> Regards<br> <br> Johan Duckworth
