Appaling Service

I recently placed an order with Telkom for an adsl line to be installed at home to which they sent me an sms with an order number: ***A assuring me that installation will take place on the 30th/09/2015 and that I need to make myself available on the day as this is an all day appointment where a technician will arrive any time between 8am - 4pm so that meant for me i needed to take a day off from work so I can sit and wait for the technician who called me at that last hour of the appointment to tell me that he wont be coming to make the installation because of faulty underground cable which I found strange because my next door neighbour in the complex has an adsl from telkom that works just fine or maybe was it the underground cable going to my unit i dont know. I then tried the following day to call Swastika on *** from the number in the sms i had been sent by telkom to confirm my next appointment with her and from the 1st of October 2015 till today that number has never been picked since i started calling. so telkom has taken my R700 deposit, pormised me a landline on the 30th which has never been delivered and they r inaccessible through the telephone. somebody help.
