Shocking response from Cell C over WiFi Calling

I bought a cell c wifi calling bundle on the 17/08/2021 from cell Cell C. It is now the 31/08/21 and it is still not working. I complained on the 24/08/21 that the wifi calling was not working even though it stated on their app that it was activated. Nothing was done on the 24/08/21. I called again on the 25/08/21 and this time they escalated the complaint. Have made a total of 6 calls to cell c each one averaging about 15 minutes or more. I had a call on Monday 30/08/21 at 09:00 from Tembi who promised to call back at 10:00. He didn’t!! Amongst the calls I had promises of managers to call me back. The only one who did call me back was a manager who called back yesterday afternoon to tell me that a manager would call me 1st thing today (Tues 31/08). Nobody did call. Even though the consultant said the manager Carl called early this morning but nobody answered. I had no missed call, so he couldn’t have called !!! This afternoon when I called, the consultant said she would get the manager (Carl) to call me in the next few minutes. I called back just after 16:00 and asked to speak to Carl. I was told after a long delay, that Carl was off today. Somebody is lying to me. The number of the cell phone in question is ***. Does anybody at Cell C care? If you want to subscribe to CELL C, THINK TWICE. THEIR SERVICE IS SHOCKING. i EVEN TRIED TO GET THROUGH TO THEIR CEO, WITHOUT LUCK. he obviously doesn't care about his customers
