Tenant keeps on pushing off repairs

[Sami Gren]

Hi,

I have a tenant that's complaining that we need to fix her ceiling because it's cracking, and we wanna take care of it , especially that is in the beed room whet she's sleeping with her toddler. .

and she insists every time that we must fix it, and we go and call guys. And she cancels in the last minute. 

same now workers were supposed to start tomorrow morning, and she texts me a few min. Ago that we need to cancel, and we can't do it before another few weeks..

I have 2 questions 

1) how should I deal with it, I can't keep canceling people in the last min.

2) I don't wanna be responsible of it falls on someone. ..

Thank you
