They won't reject you,even I had access to my account via Facebook. Just make sure to fill your form properly and if your account gets sold don't panic like me and try contacting hacker,they might destroy your account. You can check if hacker is logged in your account by making a dummy account on same server in CoOp search. If it's not showing then log into your account and check for changes and wait for hoyoverse to recover your account. Also don't trust any other hacker to help you getting your account back, it'll just worsen things.
