Locked Yahoo Acount

Hi there,

Please help me. Before i changed my password, I thought I was hacked coz when i signed off, my friend found out that im still on. Instead i changed my password to a longer one. I'm using my password for almost a year now, but lately I was informed that im using a wrong password. When I clicked the forgot my password, yahoo opened my account and I saw my old password there, when i tried to use my old password they locked my account and asked me security question which i thought I answered it right, but still i was informed that it was locked. Please help me. That email im using is my official email in all my trnsactions.

Request favorable action and Thank you so much.
