Telkom does not show up for the appointment twice

I app**** to move my phone line more than a month ago. Telkom said that in order to install the line at the new place, they have to book a full day appointment. First appointment was on 20 Feb and even though they confirmed twice they would come (SMS and via phone), they did not show up. After I followed up to see what happened they said there was a problem on the day and I needed a new appointment. Second appointment was 5 Mar and Telkom did not show up again. If I phone again, I will probably have to get another date, probably in two weeks and I will again have to make a plan to be available to a technician whole day again. I need the phone line installed (moved) ASAP.
