Intermittent internet access

For several months we have complained about intermittent internet access. Despite paying for a 10mbps ads like line we have never achieved close to this speed since inception. Nevertheless the slow speed is acceptable so long as we have service.<br> <br> Since October 2015 we have had to endure either no internet access or repeated connection timeouts or extremely slow speeds (1min to open a web page). Several complaints on the complaint line have been made and even these take days to receive a response. A couple of technicians have been out (without phoning ahead) but haven't been able to give a reason for the faults.<br> <br> We live in Glenmore Crescent Durban North and are pulling our hair out.
