How can I recover my Yahoo account if I don’t know the answer to the security question?

My Yahoo account when I log in in it doesn’t accept the password. I tried several times and I have some emails that require to be replied to. I am requesting if there is a way I can open it without answering the secret questions, since I can’t remember them clearly. Please help me!

Thanks in advance

In case of a hacked account send a mail describing your problem to account-security-help@cc.yahoo-inc.com. If this doesn’t help, call Yahoo: 1-408-349-1572, or 866-562-7219 then press on #2 explain to a customer service person what happened. They will ask you to do certain things and then they compare your original info with the changed info. Within 24 hrs you should get your account back!
