Telkom middelburg mall not answering phonecalls

I have been trying for the past week to get hold of the Telkom store in the Middelburg mall. I have since also speak to the mall management but with no success. I need to change ownership of a residential line. I am staying in Witbank. Witbank has no Telkom store and we therefore have to use the services of Telkom in Middelburg mall. I have ever since submitted the documentation to an e mail address for telkom that I found on the website, but only received an automated reply. If I try to follow up with Telkom general enquiries, I amdirected to the Middelburg store. If they don't answer phone calls how should I even know that they are there if I drive through?? Please asssit.
