HELP! Yahoo mail problem

I can’t access my email. I’m 100% sure with my password but every time I try logging in, it says invalid id or password. I tried accessing it from my yahoo messenger but i can’t also log in there. An error message pops up saying my account is locked. I tried changing my password using my alternate email but it still doesn’t work. I always get the same error messages. Can anyone help? Thanks.

A friend found his Yahoo email hacked a few days ago. Go to the Contact Yahoo page and advise them of the situation.
