No service on a business line reported 31 March'16

I reported two of our business telephone lines out of order on 31 March 2016, via the online fault reporting. Have called again on the 4th, 6th, 8th and yesterday 11 April and still no sight of a technician. We now have 3 lines out of order and no response from Telkom.<br> I stressed our urgency for the lines to be up and running, but this has fallen on deaf ears.<br> What do we have to do to get the service we deserve as paying clients?<br> <br> Thelma
