Usually they will see a line down condition as leakage to ground and
respond remarkably quickly. Once when a falling tree snapped my line I
went through all the modem in test socket palaver before trying to call
them only to discover I had no dial tone.
Ringing them from a neighbours they said yes we know - a van is on its
way to fix the line on the floor as we see the leakage to ground.
If it is as wet where you are as here then I'd be surprised if they were
not there by this afternoon.
