How can a regain access to my yahoo account?

I recently had a phone number changed and I did not set up a recovery E-mail and nothing in the Yahoo help site helps it continues to refer me to the same thing "Use your recovery phone number" which I do not have, the phone no longer has the same number since I changed services. And even if it did, this phone cannot receive texts due to the location of where live, it's very mountainous and cell towers are scarce.

I really don't feel like talking over the phone to anyone and would rather keep guessing the password until I get it, if that be the case.
