As mentioned above, there isn't much you can do to access the funds given that it's a custodial service. You just need to hope they respond to your messages but I would personally not count on it, not after reading Trustpilot reviews, and some here on bitcointalk...
Are you from the EEA by any chance?
From February 2026:
https://web.archive.org/web/20260219104607/https://freewallet.org/limitationsNow:
https://freewallet.org/limitationsNotwithstanding the foregoing, Freewallet does not solicit, market, advertise or otherwise actively promote its Services to citizens or residents of the European Economic Area. Any access to or use of the Services by such persons is undertaken solely on their own initiative and at their own risk, on a reverse solicitation basis, and shall not be construed as an offer by Freewallet to provide its Services within the European Economic Area. If a citizen or resident of the European Economic Area presents Freewallet with any document, identification or other information confirming such citizenship or residency, Freewallet reserves the right to immediately suspend or terminate that User’s access to the Services and close the User’s Freewallet Account, without prior notice and without liability to Freewallet.
I couldn't find any other snapshots, but it's possible that the EEA has only been added on June 30th of 2026 (when the page was last updated).
I wouldn't be surprised if they are using this new policy to selectively scam some customers who had accounts prior to the policy change.
