Account for Recovery

Good day!

I just want to ask on other way I could recover my yahoomail account. This is very important to me. I've been using this account ***@*** for so long. Suddenly when I log in my account there is a recovery option prompted on my screen. Now the problem is that the two options are no longer available. First option was my mobile number, I know this number but I'm not using this anymore for a very long period of time same with my recovery email address. Any other option that I can recover this account?
