Hello,
I recently discovered that someone has accessed my account [your Riot ID / username] without my permission and used cheats or unauthorized software in Valorant.
I did not authorize this activity an I was not the one playing during those matches. I kindly ask you to review the recent activity on my account and take the necessary actions to secure it.
I am ready to provide any information needed to verify my identity and restore full control of the account.
Useful information:
Thank you for your help.
Best regards,
