Faulty Business Line for over 3 weeks

We have had a problem with our business line since beginning August. <br> Numerous phone calls has been made to the Telkom helpline and the problem has been escalated 3 times already and the lines are still not fixed. <br> <br> As per Telkom the turn around time for faulty lines (as they indicated this to be the problem) is 3 working days. <br> <br> We are at 4 weeks now. Numerous reference numbers have been given and promises of callbacks and technicians being sent out to fix the lines. <br> <br> How can you stay with a service provider that you cannot trust to keep to their word and fix the problem within the time frame supp**** by one of their representatives whilst trying to run a business. <br> <br> Answers needs to be given and the problem needs to be fixed.
