No contact and no installation

I ordered my business landline and DSL line. Telkom made a booking with from last week Tuesday 24/02/2015. That morning the agent called to confirm address and directions and said he is on his way. I have heard nothing since then from TELKOM or THE AGENT!! i have tried calling the call centre 3 times since then an everytime i am on hold for more then 10mins, and i have to use my cell. I am absolutely disgusted witht he service so far.
