Vodacom overcharging customers with no proof.

I have been a customer of Vodacom for many years, and in January 2015 I received a bill for over R4550.00. This was apparently caused by my data usage. In all honesty I don't understand how this is possible seeing as I do get a data bundle, anytime minutes and also unlimited SMS every month. <br> <br> I made a call to customer care to resolve the issue,but was told just buy prepaid data bundles. And we cannot do anything about your high bill. No feedback or investigation was initiated.<br> <br> I uninstalled several of my apps and switched off the data on all my apps that I don't use.<br> Once again receiving another bill for over R4500.00 in February 2015. And again I got the same response from a customer care agent.<br> <br> This is completely unacceptable and also not possible. I have taken all the necessary precautions after the first incident occurred to avoid another bill this high.<br> <br> I am deeply disappointed and upset.<br> <br> I will most definitely cancel all my contacts with Vodacom was move my business to another network.<br>
