Line down since 09/04/2016

I recently (think it was completed on 01/04/16) upgraded my line from 2mb to 4mb, before upgrading I never had a single day of problems. Now my line has been down since 09/04/2016. I call every single day and get promised everyday that it will be fixed. Telkom hasn't even called me a single time. First 2 agents told me turn around time is 48 hours. Other agent told me 7 days. When I called yesterday I was told that I would definitely receive a call (14/04/16) and it will be sorted.... that didnt happen. Now the latest agent tells me there is no turn around time. They might only fix my line on the 22/04/2016 as per her system. One of the largest companies in the country and the largest telecommunications company in the country doesn't have staff to fix a simple problem. There has to be another solution to this. The part that upsets me the most is all the different stories from all the agents. Asked to speak to manager today and they don't have a manager available to speak to me. Escalation reference number: 849647. The upgrading of my line took long as well but I didn't mind as I was still connected on the 2mb while waiting. Now nothing.... no phone or Internet. Absolutely useless
