My business landline off more than 3 months

For Almost 4 months, my business landline has been faulty. The problem Started in the last week in october. I went through the process of finding out what the problem is. For a few weeks we had technicians coming out, eventually the buck just got passed from one to the other. Every 15 days I get the same message.....\our investigation has been concluded and we have targeted the problem\" etc. But nothing. No one has taken responsibility, I have wasted so much money on airtime my personal time going to offices and loss of income over the busiest time of year, being November and December and so has my staff, due to the fact that they work.on a commission basis.to any lawyer who would like to aid me in sueing telkom for \"loss of income\" , I would appreciate the help. My business has suffered for literally 4 months. The embarrassment we have had to suffer with regards to clients. Telkoms service is pathetic and retarded on so many levels. I'm livid and feel totally helpless that my wages n that of my staff is dependant on my landline being open and running. The most frustrating part of this, is that telkom is making money off my studio while my small business is suffering"
