Telekom cannot provide service when you need it

My landline and ADSL connection is problematic for the second day,Telkom claims they have 72 hours to try and fix it.I have never consent to 72 hour turnaround time because I am running a small business and no communication means no income,you think they care? Will I get 72 days to pay my account? Nope but they can breach service and you as a customer has to accept it. Telkom you infringe on my constitutional right to earn an income, you are breaking a law. Don't bother me with your organisational challenges because it is irrelevant to me as a customer. I will never encourage any person to deal with Telkom,rather to avoid their monopoly which makes then careless,arrogant and do expect no after sale service just excuses!
