Complete Incompetence

My landline has been out of order since early March and it is now May. In spite of repeated attempts to get Telkom to repair it through telephone calls, sms, emails and actually going in to Telkom shop in Eastgate, ( and only finally getting a response in late April) my landline still remains silent, no dial tone. They sent someone who took almost 2 weeks to replace cables which he assured me would sort everything out. My phone worked for a week. Then a team came from the local Telkom branch to do something unknown to me at the telephone pole and my landline stopped working again. I visited Eastgate Telkom shop on 13th May to report this and it is now 20th May with still no response. I have called the local branch and no one there will admit to having come to my home to do repairs, and thus there is no one who will take responsibility. I have to use my cell phone to make all landline calls.
