Urgent Needs Not Met

We had our old ADT panel upgraded two days ago, Wednesday.  We noticed later that day that the phone line in the house was not working, though it had been earlier in the day prior to the panel upgrade.  I called Telus support at around 6pm and was on with them for 28:10 while the CSR made me show him all the phone lines and connections by video-chat.  I explained that we have checked everything and we still have no dial-tone on the house landline.  I explained the urgency of the issue with an elderly family member in the house.  He said he would have a supervisor call me back within "1 to 24 hours".  6:30 the next evening, my call was returned - by then, we'd had no phone for over 24 hours.  The "escalation manager" as he called himself was advised that there was an issue and he would look at getting us a technician.  I explained it all again, and impressed the urgency.  He said he would try to get a technician might it might not happen until Monday as he said "tomorrow is my day off."  It is now 2:00pm on Friday, I am on the phone with a third CSR for over 35 minutes and explaining it all again, she says earliest appointment is June 4.  This is BEYOND absurd.
