NO RESPONSE for over a week on official complaints

Good day! Lovely to pay our account with MTN every single month, but getting NO RESPONSE from the customer care service desk when data bundles are added to the account which were not signed for in the contract. I've submitted 2 e-mail inquiries - one for Itemised Billing for which we now have to log in but have not been supp**** with any log in information. This follows after we did not receive any itemised billing for over a year as an *********** sales agent did not - after repeating the relevant e-mail address 6 times - get it right! I can not claim any company calls without Itemised Billing - and thus have had to pay myself for MTN's incompetence for over a year. And again this month I'm stuck because of your incompetence. The second inquiry is about a 500MB data bundle on my account which is not part of my contract and was not used by me, but was included on my bill. May I please receive answers now - or do I have to lodge a complaint with the Consumer Protection Forum??????
