Has anyone had luck claiming unpaid superannuation through the ATO?

I'm about to report a previous employer to the ATO for unpaid super. They haven't paid me or paid any of my previous colleagues. Ive done a lot of research into this, and it sounds like it's a very slow process and that there's a chance we may never get our money. Has anyone been successful in getting paid after going through this process? I’m owed almost 10k so it’s quite a sizeable chunk. Thanks in advance.
