There is no point in logging things on Hello Peter

I have logged a complaint with Hello Peter, stating that it is impossible to get a itemized bill from MTN. My account has gone up month on month by about R500. This month I used my phone much less that the previous month when my dad was ill in hospital and my account is R500 higher. I have been to a MTN shop. They can't help me. I have logged on to the self service portal and according to the portal my account belongs to a corporate. My account was transferred from Ericsson into my name more than 7 years ago and I have the paperwork to prove it. <br> <br> I am disappointed that Hello Peter does not follow up on complaints. It is clear that MTN has responded once and has no intention to respond again. Can Hello Peter suggest any next steps?<br>
