Data used by MTN employees without my consent,

My internet connection (data) was not used by myself since end November 2014.<br> On or about the beginning of September after enquiries that my data ****le sim card was disconnected my service was reconnected.<br> My contract with MTN is a R99 pm contract for 2 gig data.<br> I received an account for R4548.52 for the period 01/08/2015 - 31/08/2015 for ***6KB for a total of R4548.52<br> The conclusion is thus that since my service was not in operation somebody at MTN used data on my account for themselves.<br> I am considering the Ombudsman or ******** charges if this theft is not resolved within the next 7 days and a full refund of the amount I was ******** with.<br>
