Hey there,
The details on past payslips have been updated due to a recalculation of the entire balance, aligning with the Holidays Act. As a result, the amounts displayed on past payslips have changed to reflect this update, which is expected behavior of the software.
If you need to review the original payslip before the change in working pattern and leave balance, you will need to restore a backup of the payrun for that specific period. This will allow you to see what the payslip showed prior to the adjustments being made.
I'm sorry to hear you're still waiting for a callback. You can find all the details on how to raise a complaint right here, at the bottom of the page.
Cheers, Amy
