I used statusmatch.hiltonhonors.com/
and uploaded a screenshot of my card and a screenshot of an Excel sheet listing my stays from 2018-2021 with IHG.
As Corona suspended travelling the last two years, I explained this in a textfield I added on one of the pictures.
I also mentioned that I have a two weeks trip coming up and already have a booking with Hilton.
Also I mentioned that I achieved Spire with IHG in 2018.
Match was granted without any further notice after two days, showing gold in my account.
Unfortunately I do not see any expiration date, but I assume I'm on the 90 days challenge, with 5 nights to confirm gold.
Good luck for your match!
