Telkom ADSL line faulty

Past seven days no internet or short 2minute bursts of browsing time and then down again. I do not want to go through port recreation of my port, switching off the router. I have tested with a working router and it still did not work. Victor came and worked from 9 am -15:00 (15/05/2015) and then the internet was working until about 8am this morning (16/05/2015). I spoke to Sam at the call center. If this problem persist I will have to go further than hellopeter. There was a line close to us that was, and still is, giving problems and was supposed to have been changed over a month ago and it has not been done. Why am I paying line rental if they can not even sort things out and put in a new line make my service I get better??
