No service from telkom

My telkom internet line is down for the last 8 days. I've got a reference nr and everything. Everyday I phoned and all they say is the technician is busy fixing the fault. This is now day nr 8. I can't see that they take 8 days to fix a faulty line. I've phoned them today and all of a sudden they can't find my reference nr. On the telkom app I see it, but they can't apparently see it. I've asked for the supervisor and they don't have one. I can't cancel my contract as I'm still within my 24 month contract.
