Forgotten password,yahoo?

Well my wife , like all of us was forced to change her password on yahoo. She did, and wrote it down on paper,then lost it now she can't get in! Yes there is the secret answer, but try as she may it will not go through. Does the answer have to be typed exactly as it was when submitted? Period, if there was one , capitals, exact wording, digits,if digits were used, such as 55, as opposed to, fifty five. Wasn't there an auxillary question, and if so how do we bypass the first, and answer the second? We have wasted hours waiting on the phone, only to get hung up on. Frustrating!
