Vodacom has not responded after 2 weeks to a complaint

I have a subscription to Vodacom Fibre. On the 10/08/2020 I called their fibre call centre to complain about not being able to access their App, My Vodacom. The consultant said it would be reported to the back office and that they would contact me. No reference number was given by the consultant (but I do have a recording of of the conversation with him). This never happened and I called again on the 14/08/2020 to enquire. The consultant said that there was no record of my call on 10/08/2020.. She gave a reference number (SR***). I also informed her of a problem I had with incorrect billing. She included this with ref number. She also told me that there would be a 24 to 48 delay before this is handed over for repair. My earlier called was null and void and Vodacom's policy was the 24 to 48 delay on every complaint. BAD LUCK TO THE CLIENT. I have waited now for two weeks with many emails to the CEO (Mr. Mohamed Joosub) about the problem. No response from his office of vodafibre call centre. It seems like Vodacom is not interested in helping clients when Vodacom is at fault.
