waiting for telkom to install a landline

We app**** for a land line from telkom on the 30/03/2016 still waiting for them to come, I have phoned them today and after to listen to annoying ads on the line for 5 min they told me we are only scheduled for the 12/04/2016. I told her we only available on the 11/04/2016 the lady told me they won't be able to help us that day but later she will check when and put me on hold again. With that my airtime ran out and I still have no answer
