Need to talk to a human at Yahoo Web Hosting!

I purchased a Yahoo domain. I had so many problems and so little support response that I decided to cancel it. I called Bank Of America, lodged a dispute, while waiting worked on the site, actually got a tech on the phone, got it running. Called Bank Of America back, told them problem is fixed. Yesterday (three weeks later) I got a "dispute resolution form" in the mail from BOA, I can't access my domain control panel, Yahoo Small Business page denies my existence, and I can find no link or telephone # to reach a live human to fix this mess. I called BOA again, explained, they said,"Oh. Duh." and - again - promised to fix it. I can find no human Yahoo contact - nothing but dead-end links that deny my site's existence. HOW DO I REACH A YAHOO HUMAN?
