Business Internet down for more than a week

Our medical practice uses a Telkom fixed line and ADSL. Our internet has been intermittent for a few months now, and it was reported to us that Telkom had repaired the fault on the 8th of June. Our network has now been completely down since Monday the 15th of June. We have called Telkom daily to report the fault and to query the status of the repair. As yet nothing has been done and we have been without internet access for more than a week. This is unacceptable as we are running a medical practice and cannot provide adequate patient care without email communication between doctors, patients, and other professionals such as the pathology laboratory. After many hours on the phone with the call center we are still without any answers as to when this problem will resolved, and we have not been allowed to speak to any more senior consultants or management. We have been told that the query is with the technical department but we need to know when this problem will be solved, and no call center agent has been able to assist us with any solid facts.
