Phone line been dead for three weeks

I reported that my phone and internet was dead on the 21st of March 2016. Telkom advised me that the issue would be resolved in three days. Then I was told that the technicians would come Tuesday 29 March. Then I was given a firm time of 03/03/2016 at 12pm. I changed meetings to accomodate this. The technitians did not pitch up.I contacted the call centre at 1:50pm who told me that they would communicate with the technicians and call me before 3pm. It is now 3:30pm. No one has contacted me. I have had to spend two thousand rand in mobile internet and calling fees. I have postponed international business meetings due to no phones. I am further paying for a service that I am not receiving.
