Poor telkom service

My land line has been down for 3 weeks now. I have called telkom and still have no response from them as to when the line will be fixed.. All I get is excuses about that they waiting for another department to go and fix the problem. You cannot speak to a team leader or manager because they are always in a meeting. I was told that a manager will respond to my problem but I am still waiting. I was also told that I must fone them to check on progress. This is poor service. This is not the first time that I have had problems with their service. I always have fone them a few times before Any thing gets done. I have had enough of their poor service.
