My sister, who is a single mother of two young boys received a bill for $20,000 and another for $1,700.

These debts have arisen from 2011 until now. No mention of how the bill got so high.

She was informed one fine related to her youth allowance, and the bigger to her parenting payments.

She is anxious, stressed, depressed and struggling to pay her bills. They 'kindly' removed the recovery fee, but have made no moves to our knowledge to go back over her bank statements or make any moves on her appeal.
