3 Gigs of Data disappeared from my 5 gig package

On first August, 2015, THREE GIGS OF DATA DISAPPEARED ON THIS SATURDAY AFTERNOON. I was unaware of this. I was not downloading anything at the time. I never download movies etc. I have reported this and checked with both my server and a computer technician. My automatic windows update is turned off.<br> <br> The fact that my data disappeared on the first of the month makes it likely that it was ******. I am worried that it will be ****** again on the first of September 2015.<br> <br> On 15 August I was informed by text that I only had one gig of data left of my contract bundle of five.<br> <br> This caused me very serious problems, as I now had to stay awake till after midnight in order to do urgent work.<br> I also had to constantly ring your call centre to find out how much data was left?<br> <br> I have been told that only cell C staff could have purloined the data.<br> <br> Also, Moses assured me that because of the problems that I had had in July 2015 with cell C service in Phoenix, Durban, I would be credited with the cost of one month's cell C charges. Unfortunately, that has not happened. Please help.<br> <br> I will have to go the Ombudsman if this is not rectified.
