never ever deal with Telkom

One year ago , I signed up for a Telkom Broadband service. After two weeks of having this service I realised it was a con , in that they charge you a set amount , which is not enough gigs for a family to use for more than one night , then they make money by selling you more data. Therefore I cancelled this service after two weeks , using all the correct procedures. I am still being billed for this service a year later. I have spent hours on the phone speaking to various consultants , I have spent hours sending letters and dealing with various consultants , I have re sent IDs , more cancellation forms , for a year now to no avail. I have tried to return the router to numerous Telkom outlets and no body will take it. I am at the end of my teather as I am am still being billed for a service I cancelled nearly a year ago.
