Incorrect billing from DAY 1

I am extremely disappointed with mtn guys hey. I have been incorrectly charged for my contract for the whole time I have had it (almost a year). I have called mtn numerous times to get it resolved, but no one seems to have the original copy of my contract, therefore they cannot help me. I am told by your 808 consultants (whom I assume work for mtn as a whole) that I need to call mtn direct to rectify this. I call mtn direct, guess what they are not there. I have had to call since the beginning to rectify errors in billing, in general. <br> <br> Some consultants say they can see the amount I believe it should be paying of R229, some cannot. I received what you guys call a tax invoice with another amount R 284 from R 274. I am actually gatvol now. MTN better sort this out. And also work on your network, its ridiculous now. One cannot have a decent phone call anymore.<br>
