Fibre off again when there's load shedding!!!!!

Vodacom just doesn't give a rats a$$ about their customers. No communication. Fibre keeps going off when there's load shedding. I am regretting taking out fibre with them. I am beginning to worry about Monday, as I work from home. How am I going to work during load shedding as I have an inverter. But no use having a back up system if the fibre keeps going down when it's load shedding!!!!
