Cannot make contact to Yahoo to report abuser/spam.?

I try to write them but it says I have to fill in more fields. I wrote this: My accounts are apparently hacked. I get updates at the Yahoo page for people I never even heard of. I complain about not being able to get my own updates when I answer at Yahoo Answers to no avail. I want my own updates at my primary Yahoo mail inbox updates. When I have answered at a particular category like Religion and Spirituality my updates are blocked or apparently transferred to someone else's account. I'm tired of this nonsense and automatic responses only from Yahoo customer service. When I have tried to make my info at my profile page visible to others someone has been changing it to visible to connections only. Why doesn't Yahoo ever respond? This is not a new problem. I have not initiated nor do I manage any accounts except at Yahoo. I have no facebook account, no myspace, no mylife, no twitter, no utube, no nothing except for Yahoo and just Yahoo email. I am using only windows 7 and only explorer 8.
