Just trying to get ahead

I was hit twice by the RoboDebt scheme.

The first year they stated I owed money from an employment role in 2008.
I was working as a Cadet getting Study Allowance alongside my Salary — Centrelink calculated that I earned $8000 in 8 weeks. What a laugh!
I am a single parent who could only dream of earning that kind of money.

They sent me a debt letter of $3600.

I have paid that despite the fact that I knew I did not owe it, I did not want the stress and anxiety — just working to make ends meet as it is.

Then I was hit with another $3600 debt.
Centrelink stated that I did not notify them of employment I had, when you can see that I did not recieve any money from Centrelink two weeks after my initial employment — this was 2012.
I had spent 1 and half years unemployed prior to this employment, they hit me in 2015-2016 with both these Debts.

Although I made payment arrangements and was paying off the second Debt, two years in a row, Centrelink reached in and took two years worth of Tax Returns.

I spent two years discussing this with Centrelink, with the onus on me to provide the evidence.
I contacted both employment places — both State Government roles only to have to wait 6 weeks to be provided the Payslips printout.
Sadly, I was left barely surviving from pay to pay and struggled to pay rent to my State Housing home charging me $415 a week rent (in accordance with my pay) whilst Centrelink were taking money from my measly Family Tax Benefit payment.
I was evicted and pushed into the private rental market in November 2016.

I felt depressed and suicidal but did not give up, I knew that I was not at fault.

I have paid back all of this money.
I want it back and what I could not pay off my HECS Debt due to not receiving multiple tax refunds — I do not trust the Government, ATO, Centrelink at all!
