Faulty line issue not solved

Telkom keeps on closing the case number while the problem is not solved yet. I received again for the 3rd time in a week a call from a different technician to come attend to the problem tomorrow Wed 16.12.2015. after the one that phoned last week Wednesday informed me all the tests he did shows that the cable from the box to the house is faulty. I keep on logging everyday the fault now for the last week. <br> Pietie was at my house on Saturday 12.12.2015 and picked upt the syncing is a problem and said he will phone me again on Monday to check if the problem arise again. he was away 5 minutes and the same happened again, line drops so many times that I dont have a connection. He asked the office again to log a call, just to hear that Pietie closed the case 8 minutes after he left my house. He also never phoned me again on Monday to follow up. This problem i have been experiencing on and off for more than a year now and has an email of last year Oct that I had the same problem. currently the last 3 months it was almost 80% of the time off.
