Telkom's Customer Service 'System' is Broken

We reported a fault on our Telkom internet line 6 days ago. After hours and hours holding on the phone to Telkom, promise after promise of a call back from a supervisor or a call from an engineer (not one single person has called us) we were finally sent an SMS 2 days ago saying a technician would come out between 7.30 am and 4pm yesterday. After 4pm we were told (after 45 minutes of holding on the phone) the engineer had 'gone home' and would 'email us'. I wait 53 minutes on the phone this morning to find our fault is then no longer booked in and will be rebooked. The process starts again. Telkom Customer Service are not 'allowed' to speak to the technical department so operates with no information. There is an online 'system' of 'notes' which is not followed through or followed up on. Nobody is accountable. We are a business with staff running without internet for 6 days and have a supplier incapable of offering support when a problem arises. We are currently awaiting a call. We know it won't happen. Obviously looking for alternatives to Telkom as can't live with this lack of service and support.
