ADSL been down for 3 weeks and no action

I am very disappointed with Telkom ADSL... My ADSL has been down since the 29 March 2015. I raised a query via the social media team and they impressively responded in less than a day... However, I was told that my ADSL was working according to their online system but it is not!!! I have been requesting for assistance since the 31st March and been promised that the matter would be escalated to Management for expedition... 3 weeks now and I am still waiting. I am an MBA student busy with my research and it's unbearable not to have working internet at home. I have further logged a fault no. 831CRK140415 but been told it will be resolved within 6 days which is still unacceptable...
