Reaching a Management person that actually resolve a problem

I am a senior citizen.  I DO NOT HAVE A CELL PHONE.  Nor do I want one.  I have been advised through LifeLock that on May 30th my email and password have appeared on the dark web.  They suggested that I change my password.  It is impossible to change because I do not have a cell phone! I spent all day yesterday either talking to agents 3 to be exact and then waiting for a call back that never came.  Just because I am old, I should not be shut out of being able to do things with my account.  I can't manage my wifi because I can't get the app because I don't have a cell phone.  This is ridiculous.
