MTN contracts ***** just never ends

So the ongoing upgrade disasters and overcharging continue. Again no-one can help and I receive sms's telling me my issues have been resolved despite there being resolution or even any conversation between me and the person closing the issues. The saga continues 1. ********** 114 did not receive its contracted airtime at the end of June. I received an sms saying its closed and resolved, but have still not received the airtime and I was forced to load R100 on the phone at the beginning of July and will have to load more before the 27th

2. Ref 1- ********** 8436 for ********** 232 which is my 2 gig day/2gig night tablet deal for R199. And this contract was signed when there was also the double your data promo running, which I was led to believe I would get at no extra charge. They are now charging me R199 for my contract AND for an additional 2g recurring data at R249 WHICH I DID NOT ASK FOR OR AGREE TO!!!! So far I have been overcharged R750 and despite logging this at the beginning of July, have heard NOTHING from MTN. Please can the Hello Peter team help
