Noboby is responding to my complaint since May!!!!

On the 10th of May 2015 I filed a complaint that I got charged for data when I had more than enough data available when I do the *141# check. I've got screen shot photos to prove i had more than 400mb available. I've phoned MTN about 5 times and have written to Hellopeter about twice already. I've spoken to a manager at the call centre today, but this IDIOT tell me one thing and then totally something else again. First this IDIOT tells me that *141# tells you how much data, talktime you have left. Correct. Then when I tell her that I've got screen shots of my *141# telling me I've got x amount available she then comes back and tells me *141# refers to how much you've spent already. See what I mean by IDIOT? Can someone get back to me to sort this out please???
