No telephone line

On 1 March we started experiencing a static noise on the telephone line. Reported the fault to Telkom on 2nd. A few days later I was informed that the fault was resolved. The noise persisted. On 8th we reported the fault to our ISP Afrihost because it was affecting our internet connection. They tested the line and reported a fault to Telkom. The next day a technician came out. He was unable to hear the noise on speakerphone even though my 72 tear old dad heard 3 meters away. He said that he would test outside but since it was late he may not come back that day. The following week he phoned us and said that he was working on the underground cable. He provided no further information. On Wednesday 9 March at 10:20am the telephone went dead. We have not heard anything from the technician since. People and businesses in the area also report that they have no telephone. When I chatted with someone on Telkom's online chat system all he said was that a technician was assigned to the case and that if he needed ti speak with us he could. I asked for information about the fault, what was being done and how long we will have no line. I got no reply. This is costing us lots of money.
