Non-existent repairing service to physical line

Our Landline has been broken for a few months and reported and after a months and weeks did we get an SMS stating that a technician will come. The tech promised to come the 8th Aug, but never pitched. When we called, another Sat was booked as we are not available during the week. Then that tech also did not pitch. <br> Again, we got an SMS to for the 19th Aug<br> That for between 7:30 and 16:00. My wife was at home and at 15:30 we called the call centre. I spoke to Queen and I told her that it is now 15:30 and there is now 30 min left. I ask her where is the technician. She said why am I saying its 30 min. So i told her that the SMS said between 7:30 and 16:00
