Help me please !

I have contacted Telkom almost 2 months ago to have an ADSL line connected at my premises. A technician did come and picked up a problem and said that he needs to sort cables out before he attends to install a line. It has been almost a month since his visit and I have called Telkom several times enquiring how much longer with the process take. I have received 2 calls from Telkom advising me that a technician had been instructed to come in tomorrow to attend to the installation. The technician never showed up. I called Telkom again on the 09th March advising them that I am still waiting. I received a call from Telkom on 13 March advising that a technician was due to attend to the installation on the 14th of March. Today is the 16th of March and I still have not heard from the technician. My wait has been almost 2 months with no results. I am now at my wits end. This is absolutely no manner to be operating any business. I am frustrated and tired.
