Why can't I login into Facebook? says can't login to facebook

Every time I try to login with my email it says
Can't login to facebook We noticed some suspicious activity on your account that needs to be reviewed. Until then you won't be able to access things like your News Feed or messages. Learn More about why your account might be disabled. My friend didn't do nothing wrong and he tried to appeal a disabled account form and it says its not disabled no need to appeal that form.

He can reset his password easily but still can't login into Facebook he also tried filling out that appeal My Personal Account was Disabled it also doesn't go through says Incomplete Form" He filled it out correctly. I don't know what is going on been 3 days now
