Vodacom Fibre

I am so frustrated with Vodacom call centre. All they are interested in is "is it a Vodacom Router" as soon as you say no the lights go off and you just get the same answer over and over. We are paying a monthly R1500 for service with no support if you do not use a Vodacom supp**** router. We have been using a Asus router since the installation in 2017 and had no problems. In the past two months at and specifically the past two days our internet stop working at 12:30 and will come back on after 20:00. Vodacom have no way of telling me that they have failure of equipment due to load-shedding in Port Elizabeth or else where in the country that can effect our service. Telling the call centre people over and over that they must log a complaint that the problem can be fixed, I get over and over the "sir its your router you should use a Vodacom router". I want to jump of a cliff these people are driving me nuts.
