Number does not exist/ *********** consultants

I have ported my number from Vodacom to Telkom in 2016 , but soon after porting i realised that i don't receive calls from landlines, i called Telkom technical services and they assured me that the issue has been resolved....but to date i still don't receive calls from landlines and i am losing a lot of opportunities , when people calls me they receive " The number you called does not exist" I again called the technical services, the consultant told me that the issue will be resolved within 24 hours, when i call after 24 hours they told me that the previous consultant did not open a new case as a result they need to open a new case and it will take 7 working days to get resolved, i again called after 7 working days and i was told the same story " The consultant did not open a new case" and had to wait another 7 working days. when i call again today they told me that the previous consultant did not assign my case to a technician so i need to wait another ****** ****en 7 days, what the HELL?
