terrible customer service

I received a statement on 2Jan which I wasn't too pleased about therefore contacted the callcentre to query this. I was then told that I am now paying for data which I never did for before. I asked for the data to be cancelled immediately as I hardly even make use of it, and besides I lose network all the time on the road. I was then told that I need to go into the store to change to a month to month contract.<br> So I went to the store on 15Jan and was assisted by Mluleki at the gateway branch. He advised me that the system is forcing me to upgrade therefore he will cancel my contract, change to prepaid and then take up the month to month contract. He advised that he would contact to let me know once it has been changed to prepaid. I have been trying to get hold of this guy as he never kept to his word and to date am still waiting to hear from him, as it seems my subscription has been updated however I have my previous balance as well as new balance which means I am once again going to get charged for data that I have not even used. This has been a total nightmare and I am so close to cancelling my contract completely and looking elsewhere if this does not get sorted out.
