Yahoo mail login redirected to Verizon webmail

[eeyore13]

When I try to log in to my Yahoo! Mail account, I get the following message:

Your email account needs immediate attention. Please go to https://webmail.verizon.com to complete the necessary steps to access your email.
Sincerely,
Your Customer Care Team

Problem #1: When I go to Verizon to try to log in using my Yahoo! Mail credentials, I am told my account does not exist

Problem #2: When I log in using my Verizon Fios account credentials and go to "webmail" I am not shown any "necessary steps" to access my email. What are these "necesary steps?" It would be nice if the original message would spell them out...

Problem #3: I cannot find any further record of this error anywhere on the Verizon or Yahoo Mail help pages. I'm left completely in the dark AND without access to my email.  I've used the Account Recovery function to send a text message to my phone to let me log back in, but when I enter the Account Key code that is texted to me, I am taken RIGHT BACK to the same error message I received at the beginning.
