I was slugged with this dent out of the blue. Ir took hours on the phone to just get a letter semt put how ot was calculated, and it quickly became clear that this sham accounting should be completely illegal. Anyone who has even a little sense can see that. I was lucky, I only worked one job in that financial year and i kept all my payslips and xould get my bank statements to disprit. I ended up owing just $300 due to their system error, not mine.
Its utterly fraudulent
