Excessive Data Billing

Mantoa thank you for your response: REQ:***. Can you please explain if the questions that I have posed previously have been answered? Because your response on Hello Peter merely mentions what I have been already told, and I do not accept that response. Can you please explain to me as to how I have used that 9GB? Can you explain as to how everybody as per comment on MTN Billing IT Web has been complaining about over billing in the very same month? Is it not possible that there could be a technical problem with MTN? I would like to know that if you say that I have used 9GB for the month, how much of data was used per site, because I still maintain that I have been using this 2GB data for 8 years and I have never exceeded up until Sept 2014, after querying in Dec 2014 I was given a refund for incorrect billing and then it started again. PLEASE CAN I HAVE THESE QUESTIONS ANSWERED BECAUSE I AM NOT CONVINCED THAT I HAVE USED THAT AMOUNT OF DATA
