Six days to fix phone line and internet?

Came home on Sunday after a trip to find out that land line was dead. Logged the fault immediately. On Tuesday I phoned from my mobile because I hadn't heard anything. They told me the technician will be there on Friday only! Six days without land line, which I also use for telkom adsl. I work from home and need internet! According to the help desk there is no fixed period in which a problem should be sorted?!
