I've heard something similar before. I repeatedly tried to resolve the issue of a refund amicably through Charles, but, like you, he suggested that I contact him later, citing a heavy workload. I periodically wrote to him and in the end we got to the point where it all started "no screenshots of deposits from the email - no return" and no other options are offered or suitable. Time wasted. As a result, more than a year has passed since the hack (output scam) and you propose to wait again, it is not clear what and how long.
Nayiem, we are adults and let's get to the point. Do you agree to accept refunds for users who can sign the address? (or offer some of your conditions for confirming ownership of the funds, but that it would be feasible for all users, and not the circus that you came up with email screenshots, requesting them almost a year after the event).
Give us a clear YES or NO answer. If you agree, then announce the approximate terms, if not, then we will use other means to get a refund from you. We need to count on something and plan our further actions.
