Line still not installed

Phoned Telkom to have my account I had activated again. When I spoke to the Consultant se checked and advised me that my old number is still available and she would request the number be activated again with the install order. Got an sms from Telkom that the technician was dispatched with ref ***. I requested they phone me on my number before coming out to confirm that I would be there. Nobody called. The technician arrived early the morning and my father in law did not know that I am installing a line. So the technician left without phoning me. I have been trying since then to request the technician phone me to me and do the install as I need it for work, and need the line installed asap. The line was previously installed at this address. No one can assist or escalate it
