ADSL Faulty

At 09h10 on 30/07/15 the Business ADSL line stop operating. We immediately try to report it to Telkom. After trying twice with their phone ringing for more than 40 mins I decided to report it personally at the Telkom Tyger Vally branch. In my presence a email were send by their service dept. and I was told that somebody will phone me to confirm a date and time to fix the problem. Nothing happened and this morning (31/07/15 we phoned again. After a hour Telkom answered their phone and again we reported the faulty ADSL line and the urgency to take action, A reference nr. were given to us (24BWK 310715). Now, eight hours later nobody has contacted us yet. How can a business in SA who is totally depended on such non existing service survive and build capability to employ more people if this is the case. To whom at Telkom can I send my invoice for loss of income ?
