Shocking lack of regard for customer service

Despite numerous calls to Vodacom regarding repairs to a damaged fibre cable on my elderly and unwell parents property, I have received no assistance from Vodacom. The internet has been down from Monday 30 March. Despite there being a turnaround time stipulated, we were advised on Wednesday, that no technician had been allocated. Eventually after speaking to a Supervisor, we were advised that a technician would be assigned and assured that the long weekend would not impede or impact on the repairs. Upon calling Vodacom again on Friday, we were advised that a technician was now allocated for 06 April. After me advising that this would nit be acceptable, a note was made on the call log indicating that they would try to reschedule for this Saturday 04 April. When I called on Saturday, i was told that technicians do not work on a Saturday and I shouldn’t have been promised this. Despite advising Vodacom that that my parents re**** on wifi to communicate, Vodacom has shown zero regard for this, and displayed a shocking lack of regard for customer service or any efficiency at all.
