Terrible after sales service

Terrible after sales service. My fibre stopped working on Tuesday and I logged a call with Vodacom. As of Friday, having called the call centre multiple times, I have still not recieved a date or time for a technician to come and assist. I work from home and have had to purchase a lot of data to make up for the lost internet connection. All of the consultants have tried to help but claim that the work is outsourced to Nokia and they can only escalate the matter, the call centre and first line reporting have been helpful, but the vodacom systems and 2nd line management have been useless in assisting with the problem at hand.
