So the dispute on PA is not officially closed yet? Can you get them to confirm that?
Also, if the dispute concludes in favor of @Mistamo you obviously will not have to refund him the account.
@Mistamo you must understand that incase you continue the dispute on PA to get a refund from there, there is nothing we can do here until we know for sure if you'll get a refund on PA or not.
I would also like to add that in the meantime you can already go ahead and recover the account with the help from @extraenigma if you wish.
