Unrealiable and poor service standards

I app**** for a Telkom line on 29 March 2016 (***). I was told that Telkom will notify me via SMS as to when they will be instaling the line. I received an SMS on 11 March 2016 (***) stating that they will install the line on 15 April 2016. I call Telkom in the afternoon of 15 April 2016 only to be told that they are not sure when they will install. I called again on 16 April 2016 (***) and was told that the matter has been escallaleted to the back office and i would be receiving their call soon. I called again on 18 April 2016 speaking to Sthandeka Skhosani from Springs call centre and i was told that they will install on 20 April 2016. I called again on 19 April 2016 to confirm the time of installation but they sent me from one department to another. On 20 April 2016, i called Telkom to confirm the time of installation but was told that they need to escalete the matter to the back office AGAIN. I was then told that they will come and install on 03 May 2016. Telkom has a very poor service standards.
