ADSL line down more than 2 weeks

My ADSL line has now been down for 15 days and what a mission. I've logged the issue on 19 Feb 7:20 in the morning. No feedback unless I phone and hold on for around 15 minutes to be told Telkom has assigned a technician they can do nothing. So far 3 technicians was assigned to my issue and guess what...My ADSL is still not working. My issue has now been escalated twice. Yesterday I spoke to a person at Mweb who told me he will phone me back today and keep me up to date. Well don't see that happening. We are now going into the 3rd weekend without and ADSL line. How is it possible to run a company on such bad service.
