If you are a job seeker, such a low-level mistake is very bad for you. Even if you receive a job, once people know that you have not filled it out carefully, they will consider whether you will be hired in the end.
The recruiter is a bank and has high requirements for job seekers. Of course, they don't want to recruit someone who even wrote the wrong contact email address.
If you still want to remedy it, contact the relevant personnel in charge of this recruitment in time and tell them that your QQ mailbox has been stolen or infected with a virus, and you can't send and receive emails normally recently. You want to resubmit them.
Don't say you are mistaken, so I won't go into details. Then you give them a new email address, preferably no longer a QQ email address)
