A form that I spent over 50 hours building no longer shows revision history and I've contacted Support numerous times before and they haven't helped

I invested over 50 hours in building this form and when I ran a test, many pages of calculations had lost their formulas.

I looked to go to a previous version and the revision history did not show up.

I had requested help, and was told it was sent to support but I haven't heard back and they did not find it.

What Can I do?

I did download my data backup on the 16th, so I have that backup, but haven't heard if it can be used to find the previous revisions.

I am very frustrated with the lack of support and follow through especially after investing so MUCH TIME in this form.

Please help.

I can relate to the frustration that this issue is causing. You should receive an update in the other thread you opened a few days ago  which was reported to L2, so I have increased the priority for that ticket.
