Centrelink

I may be misinformed but I thought that Government Departments were open five days a week.  Well today Elizabeth Centrelink was closed.  I rocked up ready to ask questions and the door was closed.  Admittedly, there was a lady outside talking to a few people but I was so cranky that I turned on my heel and left.  No only was the door closed the shutter was closed as well.  Talk about giving people the hint.  I still think that going in to Centrelink is preferable to ringing them.  Ringing is a form of water torture.  "Thank you for your patience, your call is important to us, blah, blah, blah."  This followed by hideous musaak and repetitive versions of the above.  I wanted to ask Centrelink why, when I only have two modules to do to get my SACE that they have cut me off the education benefit.  I have always wanted to get my year 12 but now when the race is nearly run they have locked the door on me both literally and figuratively.
