Success getting Gil restored that was removed by a compromised account?

[Berkilak]

Oh and one more thing. SE saying that any gil earned by your friend after the incident will be lost is because of the rollback your friends account will get. That includes gear, items or any gil after he regains control of his account. It can take up to a week to 10 days to rollback. Your friend just needs to be patient for that long.

That's the thing - they rolled back their character without really reading the fine print or checking to see if the FC chest was compromised. So their character did withdraw the 70 million, but then they rolled back their character to right before they did so.
