I signed into my account and noticed that since the last sign in, ALL e-mail in my main inbox had disappeared. I'd been with Yahoo! for 21 years & even tho' I clear out a lot of mail, that's a LOT to disappear. I tried to make several requests for them to recover it, but got no response. There's no one to call, no way to tell them what went wrong, I basically just have to eat it. Don't ever use Yahoo! for anything important because you will have ZERO support or help if anything goes wrong.
