I believe I did file a claim then but it came back empty. At the time it was only a few hundred dollars and not worth putting too much time into pursuing (or so I naively thought). Been having sleepless nights recently wondering what if so thought I’d ask here in case anyone knew of other ideas.

Edit: I found an old response and yes, it was rejected as the amount I put in wasn't found. It's tough as I don't recall the exact amount of BTC I had in the account.
