If I buy account from you and make deposit, then there is a possibility that you can appeal ticket to recover the account. and you have the KYC related documents, so you can easily recover that account by contacting with support.
no he cant recover it cause website not only ask for document to give back the account they ask to show deposit and widraw and only the person who did deposit and widraw will know that info not the guy who make accounts also its always recomendable to change all info on account email ect so no one can recover it
