|Is this BTYahoo (ie do you have a BT email address assigned to it?) or Yahoo webmail If it was BTYahoo then you may be able to get help from their customer help system, if you have details of the account that pays them. However if it is Yahoo webmail (the free one) then you have fewer options. |
Was the 'secret question' your only recovery option? You should have been hassled by Yahoo over the last few months to set up an alternate email address or mobile phone number. Without either of these it is extremely difficult to get your password reset as Yahoo have been targetted a lot recently by hackers and that may be the problem in your case.
