Bad Service for Fixed Line Installation

Ordered a fixed line with ADSL and selecting Telkom as my ISP at the beginning of May 2015 via the call centre 10213. I was informed installation will be in 7 to 10 working days. I followed up on 25 May 2015, to be informed that there is no order on the system. A new order was generated same day. On 11 June 2015 I follow up to be informed 1st, there is no order, 2nd that there is no infrastructure. No one ever came to my house or called me to confirm this. New order was created on 11 June 2015, now with confirmation of installation on 18 June 2015. No one arrives or contacts me on the agreed installation date after I arrange from my in-laws to wait at my house the whole day, On 19 June 2015, I contact Telkom to be informed that the technician claims no one was at the house. I insisted on Telkom correcting this, I was issued with a new installation date 06 July 2015. When Telkom contacted me the same day it was agreed that this is unacceptable and I will be contacted with a date closer to the original 18 June 2015. It is now 25 June 2015 and Telkom has not contacted or corrected this. Our complex was completed in 2006 and fully occupied same year.
