Locked thermostats not on the app

[IDDPThermostats]

I need help on resetting a nest learning thermostat that one of my users put a pin on and doesn't remember it.  Unfortunately, they removed it from the app as well so it's locked and I can't do anything with it.

The only way to unlock a device with a forgotten PIN is to contact Google Support.  They will send you an unlock file after verifying ownership,

I was hoping one would contact here and let me know how and all, but no go so far.
