Delays in attending to fault. No communication provided whatsover

I've had no internet connectivity since Sunday. I logged a ticket with Vodacom who is my ISP who advised that the issue was due to the fibre line and that a ticket would be logged with Vumatel for a technician to come to my house and attend to the issue. I was advised that Vumatel was required to attend to tickets assigned to them within 72 hours. It will be 72 hours this afternoon and nobody from Vumatel has contacted me with regards to this issue so it likely won't be attended to within 72 hours. Extremely frustrating when a company does not keep its word at the expense of their customers!! Yet we still pay you!! Please attend to my issue.
