Random person linked under my account
Context: I was hacked on the 30th July 2025 and lost access to my Genshin account. My account has been unlinked to my main email and I do not have the ability to log into my account. I did not submit a request to customer support as I do not have proof of ownership (receipts, payments + screenshots) and the likelihood of them listening to my claim of being hacked is unlikely. Recently, my friend sent me a screenshot of an unknown account that was linked under my Hoyolab account. Their username was very unique and I was easily able to track this person down and find their tiktok account. My plan is to talk to them in hopes of retrieving my Genshin Impact account.
How do I approach this situation?
Their username will be kept as confidential. Any suggestions will be greatly appreciated.
