Unfair additional charges

Hi, we have been trying to cancel the 147 Plus for R 10.00 (we have no idea what this is for), R 2.63 for a quick sim (again we have no idea what this is) and the itemised ebilling. We have been going into Vodacom Key west every month to do this. Every time the consultant phones through to the head office, or emails or does it on there side. Every month we get charged again. So far you have ****** a pensioner of R 25.54 per month for a number of months. The funny thing there is two of the same contracts on the same name. Both upgrades were done together and only on the one are there all these extra charges. I hope someone comes back to us and sorts this us ASAP.
