Mislead and Overcharged

I have been a loyal customer of Vodacom for over 10yrs and to date I have 8 lines with them. In May 2015 I took another contract for R99 a month and before I started using the phone, I called the call centre to put a limit as this was for my 6year old daughter. The lady that I spoke to confirmed that this was a Data only top up contact and that if the data is used up, I can buy additional data.<br> <br> In June, the phone was misplaced and I called the call centre to block the number of which I called back to reopen on the 17th of December 2015.<br> <br> To my surprise end of Jan I received a bill of R996.67 and I was told that this was due to over usage for December. I requested a statement which showed another over usage of R1783.94 for January. I queried this and requested an Itemised billing and I was told that an agent from the data department will call me as it doesn't make sense for me to pay this extra amount of R2780.61 for only Dec and Jan.<br> <br> I have been waiting for the call for over 2weeks and need an investigation with the call I made which mislead me to the extra charges I am faced with today.<br>
