Paxy,
Just to let you know, rosters are wiped on a rolling three day basis when people are sick so work normally becomes available then.
Use the 'voice' number, select option 4, then as you say press '#' to speak to an advisor. From what I remember they are there from 0830 til 1630. If you get a blank line hang up and try again. It seems to 'hang' occassionally, especially after 1600. Perhaps they don't want to speak to anyone then! This is only for work after day 2. ie not today or tomorrow.
They are always very nice, and try to help as much as possible.
They are other ways to get more work but, they are something you have to learn as you go along
