I am sorry to say but the QL:D act says you will be paid the rate of pay that you were earning in the 12 months prior to the accident.
Here is the link and you can work that our.
As such you will have to pay it back to them because you have been overpaid because of the rate you were on before the accident.
Even though you were to go bak on your full rate when the contract was over, because of the accident you are not entitled to the overpayment.
I completely understand you may not have it to pay back but you will have to repay it. If you can afford to repay it by instalments or reach an agreement where your payments stop for a period until it is repaid these are your best options.
I am sorry I cannot be the bearer of better news.
But this is how the act applies.
I hope this makes sense and is of assistance, If there is nothing further
thank you for using my services.
If I have missed anything, or you have any further questions please let me know
If there is anything else in the future please do not hesitate to ask.
