Landline issue since 21 August 2015

Raised a fault re landline 21 August via the sms method, the line is crackly. Received a call from Telkom -on landline, and the lady called me on cell as she couldnt hear me. Since then I have raised the issue twice with Telkom where they have said they escalated the problem - but still no-one has been near the house to resolve the issue.<br> original complaint logged: 408CRK210815<br> 2nd escalation reference (didnt get one for the first) 737797 dated 3 September. Although my ADSL is working, I still need to use the landline for calls.
