Unable to help me with my line

I have moved my line to my new house on the 29th December 2017. I booked many appointments, probably about 5 appointments to install my line. I have spoken to 2 managers and I was told they will install my line as the problem at the exchange is now fixed. Nothing has happened and not smses have been received about an installation date. I phoned again today only to be told there is an issue with the exchange and nobody can help me. I am needing some answers as I don't know what's happening with my line. Telkom has been unhelpful and can't give me answers. I am fed up with this.
