Haven't had internet for 13 days!

I contacted the call centre 13 days ago to report that my ADSL line was not working. Since then, I have been subjected to countless call centre agents taking me through the EXACT SAME troubleshooting that has still done nothing to solve my problem. Not only is procedure this not recognised as a problem, all call centre agents are quite nonchalant, none-responsive (never call when they say they will), and quite happy to repeat the same thing over and over again. I, a small business owner on the other hand am stuck with no service, higher bills for internet access using mobile provides and the inability to move to another supplier because they can't access my modem because Telkom has done something that does not allow them to do anything. This is unacceptable to say the least! How am I meant to run a business and create jobs when Telkom is stopping me from doing my day-to-day work? This is unconstitutional and an absolute attack on the growth of my business! I am beyond perplexed by the manner in which they handle faults and complaints and would seriously suggest that they start by solving my problem, and them going into their processes as they are totally irrational!
