How do I reach a live person in Yahoo! Groups support?

[Sean]

Several years ago, my boss and I were subscribed to a Yahoo! Group without our consent, and since that time, our corporate e-mail domain has changed, so I'm unable to use e-mail commands to unsubscribe from the group. What's more, the group moderator has never responded to an e-mail sent to GROUPNAME-owner, so there is no way that I can unsubscribe our e-mail addresses. And if you've ever tried to find a live body at Yahoo! Groups to direct a service request to, well, then you can understand my question. Does anyone have a phone number, Twitter handle or e-mail address that belongs to a living, breathing human being who can go in and delete our two e-mail addresses from this Yahoo! Group? The group is global_desis (neither of us are Indian, so again, I'm stumped as to how we were subscribed). Thank you!
