Telkom ZA Cant resolve faulty line in 15 days,

I'm subscriber of Telkom SA ADSL. My line is faulty since Nov 10th, lodged online complain 394CRK121115 on 12th November. Issue still not resolved, Had called Customer care everyday since then No luck, twitted them still issue not resolved. One technician came on 23rd November and said Line is faulty and it'll be resolved soon but still Nothing happened. In mean time I had changed router also and checked to rule out problem at my end.
