I had a problem that developed with my free Yahoo email acct last Tuesday, where ever saved email in my account older than July 3rd was gone. I knew I did not even accidentally delete anything, let alone I have about 30 different folders (no way I know of to do a 'super'-delete).
I emailed them (as you, you go to Help, tell it it didn't help you, and it brings up a small window to send info). Sent about 5 differerent submissions. Thought I got a reply back over the weekend (had a case number in the title), turns out no tech information, it was a link to a survey on how customer support handled the case. Needless to say, a lot of goose-eggs (0's) on that response.

I did find a phone number (408 area code) for Yahoo support, but it says not surprisingly there is no live support for the free services. I'm almost tempted to pay the $20 to get the Plus/Platinum email package, just so I can be entitled to call them up and find out what's going on. I'm assuming (hoping) Yahoo makes periodic backups, so there's a chance I might get some of my messages back.
