Telephone line fault

I reported a faulty business line at Telkom on the 09.02.2015 to date the line has not been repaired. When I did a follow up call with Telkom, after being on hold for 25 mins I was told that the fault has been closed whereas we did not get any visit from technitians. I re logged the call, on follow up again same story. I logged the call again for a third time but still the line is not fixed. PLease bear in mind that this is a business line and we depend on it to fulfil our mandate.
