We have been complaining till the steam come from

We have had the land line in for more than five years and have opted to have it on a prepay system as we dont find any use... for the last couple of months we have had no service and when ever we complain the say they are working on it. We recieve absolutely no calls and cant use the phone even to make outside calls- our adress is : 52 Laingsberg Road <br> Heideveld , <br> 7764 -
