Yahoo No communication nor help from Yahoo. URGENTLY need help  Internet

When Yahoo went down (again) a few weeks ago, my account was locked to me.  My password wouldn't work and the loop they put me in with trying to answer security questions was very frustrating. 

I wrote to them 9 times now with no help.  I called twice but was told from an automated voice that they couldn't help with problems like that over the phone.

I am the VP for Development for an international non-profit and have all my saved email and contacts in my account.  I desperately need them. 

I've since opened another Yahoo account but still need the data from the old one.

Yahoo isn't listening.  Yahoo isn't caring.  Yahoo doesn't communicate. 

Who can help?
