Pathetic service by Telkom

On the 06 October 2018 I logged a fault with Telkom regarding my internet not working on my adsl line.They said that the line is faulty and it will take 72 working hours to get feedback and to sort out. Every day after that when I queried the progress on the fault I was getting a different answer. It's gone almost a week and nothing has been done. Once u log a call the call centre agent does not have the number to call to get feedback for customers we must just wait for answers like a fool. How does Telkom operate cos their service are perthetic and I am paying for something I'm not using. Sort out this issue
