You have proven that when a scammer calls with a lie, and gets challenged, the scammer will create another lie to trick the person who answered the phone.

A smarter scammer would have hung up after you challenged her on the second lie, knowing that further lies would be challenged.

The smartest scammers will hang up after the first challenge, because they realize the person who answered the phone knows they are a scammer.

did not take call, called # back and brief message comes asking for your full first and last name.  No one I know would ask for this.
