Vodacom fibre bad service

I very much regret signing a contract with vodacom fibre! . Our router that is less than two months old packed up. 3 days later and after numerous phone calls to the call centre (they refuse to put you through to management) we have not received any feedback or heard from them at all. We have been told that if the fault was due to load shedding the warranty is not valid and we will have to buy a new one. They cannot tell us how this will be established. We were just told TO WAIT!!! The entire experience with vodacom fibre has been nothing but extremely frustrating!
