Poor Vodacom Fibre Support

or the past week,i have been contacting Vodacom in relation to our fiber that is non-operational, when i contacted Vodacom, i was advised that there was an issue on Nokia's (Router) side, 1 day later, I contacted Vodacom again and was given the same response, i contacted Vodacom Fibre every singe day for 7 days , I finally spoke to someone that was able to assist me and advised me that the issue was with Vodacom and she then logged a call, she advised me that it would be a 24-48hour turn around time and that the technicians do not work on weekends but to expect the technician on Monday, this morning when i called Vodacom fibre, i was told that the service request would take a further 24-48 hours to be assigned to a technician so they cannot provide me with an ETA of when the technician would get to my residence.,Everyday they say "An email has been sent",This is Affecting my Business greatly and their is still no soloution
