non existant fibre from Vumatel. No interest in assisting customers

I have been without fibre for 4 days now. The customer service is non existent. Absolutely nobody has called me to make an appointment. I have spent a fortune calling your call centre at least 6 times a day and buying data so that I can actually do my work before I get fired!. All I get told is that the call is with a technician. Said technician has never appeared. How am I supposed to work with no fibre to the home? I have teenagers doing online tests that they had to complete at other people's houses late at night. When is someone going to call me back? the call was escalated on Thursday and nobody has phoned me despite many many promises of this happening. I demand a credit for all this downtime, but first fix my line!! your message while waiting in the call queue is ridiculous "we believe everyone must be connected" - what a joke!
