Land line problems yet again

Just got back from vacation and was messaging/posting here while I was away.    I see that my home land line has been activated and the correct phone number shows up on the Telus app and also when I make a call to it from my cell phone.   Now that I am home, I realize there still isn’t any dial tone in the house.  I need this fixed.   I started dealing with this two weeks ago!  This also means my home alarm system isn’t being monitored because i don’t have cellular backup - it uses a land line.  First off, I would like to get the home land line working. Secondly, I would like to cancel my home security thru Telus but I cannot get thru to them.   I’m paying for things which are not functioning.
