Un believable how bad service providers have relaxed on client satisfaction

If it was possible to give telkom a negative rating I would. For the last couple of months my adsl line has been on and off. It takes the a week to repair it and I loose income due to this. Once again I had deadlines this week. On the 10th we were told 24 to 48 hours. It day 4, I still have not been able to meet my deadlines and they have yet to answer me on where I should submit my claim of the lost income.
