NOTICE THE DATES?
Now how is it that I cannot sign in to this account or ANY OF MY OTHER ACCOUNTS despite the dates and despite the FACT that I have signed in to all accounts since SEPTEMBER OF THIS YEAR?
Answer the questions and explain instead of just ignoring this feedback.
I cannot change my passwords or verify non Yahoo accounts without access to my Yahoo accounts and I cannot access documents or contacts. Also one account is used to verify payments from a government pension office where they ask me to send yearly updates on my eligibility to receive the pension.
