VODACOM IS A ROUGH

It's over a year that I'm off calling 135 customer services and everytime I get the same feedback, someone from technical department will contact you. I'm still waiting for the call. I have no signal when it's load shedding both data and voice. My calls never go through or always drops... I'm tired of the lack of concern and the disgusting service that I have to pay FULLY EVERY MONTH FOR.... I've EVEN ASKED FOR A REDUCTION OR A CANCELLATION DUE TO THIS... VODACOM IS A ROUGH ... I pay R652 but can't access the network properly,this is disgusting and the agents that work there have no customer service skills or brains.....
