Lost Data

I lost more than 2G data on the 20th Jan and another 2.3G on the 20th Feb. I figured it was an error from MTN but wanted to make sure it was the case. So I checked my data balance ont he 20th feb, and I woke to 2.3G less on the 21st Feb.<br> <br> I called the call centre and was given *** and I never heard from MTN again. <br> <br> I called yesterday (2 weeks later) to follow up, and the agent assisting me advised that I had multiple apps open and that is what used up my data. <br> <br> I've had a iPhone for 3 years now and I have never lost so much data overnight. <br> <br> I tried explaining to him what happened and he insisted I listen to him explain what was clearly not the case. <br> <br> i would like this resolved and my data credited back or money refunded.
