Installation date postponed continuously

1ste- Friday 20 Nov when I signed the paper work I was told my landline/wifi would be installed the following week, after waiting 5days without responce I called Telkom, being informed that head office haven't even received my paper work, person sorted it out and on 26 Nov I got a message stating that the installation will take place on 30 Nov- I put in leave at work so that I can accommodate Telkom. On Monday no one pitched-nor did they call or inform me why they didn't pitch. Once again I called Telkom -being told the tec person was over booked and he'll accommodate me the following day- leaving me to put in unpaid leave. Without surprise they did not pitch once again!
