Technicians not showing up for installation

In July I requested my Telkom line to be transferred to the new residential address on the 1st of September. The technician showed up once, but said that he needs to check the box. From there several appointments have been scheduled and confirmed, but no technician shows up. Today a technician was supposed to show up between 07:30 and 12:00, which did not happen. I spoke to several consultants that assured me that a technician will phone me and come to complete the installation in the afternoon. They also informed me that the supervisor of the technicians for my area, Simon Vusi Mnguni, spoke to another technician and arranged with him to install my line (apparently the first technician was unreachable and his mobile just went to voice mail). The \new"technician phoned me at 15:40 to let me know that he will not be able to come as he knock's off at 16:00. Everytime I need to take leave from work to sit and wait"
