Vox Telecom service delivery

Three weeks ago our internet/wifi signal just went weaker to the point where we have had no internet for the last two weeks. That is also how long we have been trying to resolve this issue with Vox. After numerous calls, including +/- 45 minutes of waiting on the line every time, we were just told tickets were lodged. Vumatel has checked the fibre connection twice now and found no fault. Finally, a technician was sent to our house, but still no internet and no feedback for three days now. This is the worst customer service I have ever experienced, it is unprofessional and disrespectful to me as the customer. It is frustrating to get no response or service and having to contact them instead of the other way around is time-consuming. I am paying for a non-existent service! This is definitely not a 24/7 service or market-leading internet service provider as they claim.
