New install and cable fault

So on the 01 February 2018 I completed a telephone sale call for a new 10 Mb adsl line to be installed at my residence. After receiving an sms on the 07 Feb 2018 advising of the install to take place on the 13 Feb 2018 between 08H00 and 16H00. Firstly I did not receive a telephone call from the technician nor from the call centre advising of the install time. I made 2 phone calls that day to follow up on the install and neither Ralene nor Talende could assist. I then called on the 14 Feb 2018 and was advised that they would escalate to another department. on Friday 16 Feb 2018 I received an sms advising of install to take place on 19 Feb 2018. I received an sms advising that the install had been assigned to the technician who called me within 30 minutes of the SMS to advise he would be with me today. (this is the 1 positive thing that has happened along this long painful journey) the Technician arrived and checked the line and then went to the exchange and found there to be a cable fault. How on earth are you to supply me with a service, if you cannot firstly offer the service I have signed up for. Secondly, i am aware of other residence in my road that have had problems from the 24/11/2017 and you have still not resolved this. What does that make me feel as a first time client? 1. Will I get the service I am happy to pay for? 2. Will I be receiving the speed and connectivity I am going top be paying for? 3. Or will I just be another client paying for a service that I do not receive at all????

I await your urgent response.

UNHAPPY TO SAY THE LEAST.
