ADSL Been done for 28 Days

Fault ref 137CNK151117 - ADSL line has been down for 28 days so far. All the call centre does is say that they understand my frustration and that they are escalating the call. Two weeks ago I received a call from a technician saying that the underground cable is faulty Then on Monday I was told by the call centre that the underground cable is not faulty and now they are assigning another technician. A strange fact is that my neighbour has no problem with his ADSL. I have used Twitter and Facebook (weekly) and called the call centre weekly to establish progress. The worst service I have ever had is from Telkom.
