Hamster Wheel and No Response

I am moving house on 1 Feb 2018. I understand that Telkom requires one to cancel/request a line change a month in advance. On 28 December I called Telkom to attempt this, but I was on their hamster wheel for 30 minutes. I had to see a client and reluctantly had to hang up.

On 29 December I went to the nearest Telkom shop and I was told by the person who helped me that I had to make the request online. I asked if I could do it while I was there, because I wanted to be sure that it went through. So I filled in the form on his computer and I was told that someone would contact me in 48 hours.

A week later I have not heard from them yet, so I went online and filled the form again... Still no response. I filled the form AGAIN today.

I don't have time to sit on a hamster wheel, because I work with clients and am busy from 08:30 to 20:30. My phone is on and I would see if it is ringing. I also have someone at home who would answer the land line.

I refuse to pay a for a month of service that I'm not going to get and perhaps tenants who will move in after I leave abusing a telephone line that is in my name.

Very unhappy with the lack of service from Telkom.
