MTN Not Provideing Detailed billing info

I received invoices for November and December that are over R4,000.00 each. My billing history will show that I seldom use more than the 2gig available.<br> I went to the MTN shop in Clearwater on 17 January 2015 to complain and ask for a detailed listing of my data use. This was promised within 48 hours.<br> As I had no response I went back on 24 January 2015. Again I was promised that I will get the report. I went again on 31 January 2015.<br> I mailed the Customer care on 27 January 2015 and supp**** info on 2 February 2015 and again on 16 February 2015<br> I am still waiting.<br> I think it is totally unacceptable to bill without supplying the supporting billing detail on request. I also think that it is unacceptable to request the detail and being ignored.<br> I need your immediate attention to this issue.<br> <br>
