No service

About 5 weeks ago my telkom line started dropping for 45 min at a time. I thought that this might be due to maintenance on the exchange or on my line. Then went away on holiday for 3 weeks and when I got back the line was completely down. I have since logged faults with *** and after 10 days of no response I logged the complaint again that escalated it to high priority *** then again another 4 days passed with no response I reported the fault again with high priority ***. I have been to the telkom branch at eastgate mall and phoned the call center numerously ,What is going on?
