no installation of my telkom line

I have orderded a new line from telkom and they sent an sms saying they will come to install the line on the 22nd of October.they obviously did not pitch and i then recieved an sms on the 24tg of october saying a tech was dispatched and i waited a whole day for them and nothing.this morning i get an sms saying that they will come but now on the 30th of november 2015.i am disgusted with this service and i did say to them this connection is urgent.if i do not have a technician at my premises by the end of today or tomorrow i will have to change the vendor and go with neotel.ref number ***
