Ogden / Lynwood phone service out again.( copper theft )

A tech showed up at my house out of the blue. July 22nd 
The day prior (Jul 21st)I was told my appt was cancelled.
Good thing I was home.
After checking the incoming line to my house the tech said one wire had been nicked.
After inserting the line in the terminal block it must have partially severed due to flexing.
Every time they check a line, it is cut and stripped to ensure a clean connection.
I get that.
On the prior visit (service call) it must have been nicked ,then when inserted to the terminal block it partially severed.
This led to my latest of many service disruptions.
After cutting and re stripping my line again.... viola it worked.
After 13 days my phone is working again.
It's been working for almost 2 days now.
The question is for how long this time.
