Yahoo No access to Alternative emails anymore.

Hello,
I have looked every where. I need help. I have an account I know the password but I can't get passed the Verification part because the emails and phone numbers are so old that they don't even exist. I know the Alternative email and I know one or so of the phone numbers but none of them I can get on. So is there anyway to bypass this. I will say again I can Verify them if I can get a hold of Yahoo through Email but they apparently don't know how to use an email because I can't find a support email address. I have googled I have searched every thing I can think of. I have tried to get on emails I thought was one of the alternative but yet nothing.
