Poor service

My ADSL line has been down since Friday 28 September and I logged a call. The call centre agent suspected my router to be faulty. I took the router to a Telkom outlet to test and it was all fine. They logged a call and a technician came out on Sunday 30 September and during his testing found that the network card at the exchange is faulty but the service department that deals with the network cards apparently don't work on Sundays. He said he would get someone to sort the problem on Monday 01 October but no one has pitched. I called the call centre and they said they kept escalating the problem but no one seems to be bothered to come and rectify it. The technician said to the call centre agent that if he receives the call he would see if he could fit me in his schedule. This service from Telkom and open serve stinks and I feel that someone needs to take class action against these ****s as they are ripping people off. I am now still currently without my service but at month end they take my money with no shame of the service they have given me. Can anyone assist?
