Fault not fixed

Logged a fault on my line via sms because the call centre never picks up. Sms back says fault would be resolved within 7 days. Phoned after 5 days, and was told that the technicians reported that the line is working. Escalated fault. Phoned next day to find out technicians are currently working on the fault. Phoned again the following day to find out that no technician has been assigned to the fault. Apparently, telkom test your line for the 7 days and try to remotely fix it. After 7 days if this hasn't worked then they will send a technician out. Huh? So they try the same thing for 7 days (height of stupidity according to Einstein to try the same thing over and over again and to expect a different outcome) and only then do they try something different. Oh I forgot, they don't start counting the 7 days from the day you logged the fault, but when they start looking at the fault! And also, you wait for the call centre to pick up anything from 30 min to an hour.
