No service for a week on business line!!!!

Problem with cables in our area. Called telkom on Thurs to log the fault. Was told someone would be dispatched within 48 hours. It is now almost a week and still nothing has happened. This is a business line and my business is now suffering because of this. It is totally unacceptable. Part of my business source of income is through faxing services, email services and I have lost out on a considerable amount of income because of the delay in resolving this issue.
