Failed to show up

Moved to a new place and telkom had to Install my line today the 8th of July. Got a confirmation message from telkom on Tuesday the 1st of July informing me that my line will be installed on Wednesday the 8th. Took of a whole day of work so I can sit and wait for no one to show up without being informed that they wont be coming today. I had to phone telkom from my mobile phone at 16:20 to ask if the service is still going to be installed. The phone call only informed me that my line was not installed today and that they can't see on the system why not apperantly the next available date is the 15th of July as if its my problem their technician didn't show up to deliver the service. How can it be such a struggle for telkom to show up and install my line I am infact a loyal paying customer and have been for the past 3 years so If they don't install my line tomorrow I will move my services to a different company. Stay away from Telkom people the worst service in South Africa!!!!!!
