How is there be no available telephone line?

I have repeatedly inquired about activating an existing telephone line. The line is already installed and was used less than two months ago. I never received any feedback from the telkom website. Only when I call do I get a response. And the response is that there are no telephone lines available?? I am in desperate need of this line and someone used this line recently. This is in Lynnwood in Pretoria, how can you have so little capacity in the third largest city in SA?? Could you please confirm if there is no capacity left for one line?
