Technician is a no show... again....

After complaining at the Telkom Facebook media page about the Technician not showing up for a line activation (infrastructure is already here), the Technician is not arriving at my premises again. The order is not registered on their system and when I told the facebook people about it they only said the appointment is the only date that is available?? Point is I cant keep staying away from work just so nobody shoes up at my house. Please sort this out... cant the technician call when he is near the property so I can meet him there???

Furthermore, the first time the technician didn't pitch, nobody let me know about a rescheduled time or reason for not coming... so you wont even know if they are coming again...
