If you're not a paying Yahoo customer, merely using a free account, you're screwed. That's the long and short of it. Join the club. You can send email after email after email, try calling, whatever, you'll get nowhere. I've been w/o my email for THREE WEEKS!

All I can recommend is upgrading to the Plus service, at least you should be able to get support. Whether that's sufficient to grab the account back from a scammer remains unclear, but perhaps you had a credit card on file (like I did from the old payment system) that could be used to verify ownership.

Anyway, as far as support for free services, forget about it. Chalk one up to the scammers. Yahoo is WORTHLESS if you're not a paying customer. Trust me, you have a better chance of winning the lottery than getting through to this braindead company.
