Shocking service by Telkom

I logged a call electronically approximately 6 weeks ago to get my 84 year old father’s landline transferred to his new home No response was received I then called the landline 3 weeks ago waited for half an hour and was told I would be called within 2 hours with the reference number - no call received I called again today waited another half an hour and was told my father must call, which is impossible .... so no idea of when the phone will be transferred while my father must still pay for his line rental .. this is shocking and unacceptable. How does one get a landline transferred???
