Realtor or Mortgages?

I got a call last week from a gal that said she was with ....Real Estate Company and helped my Realtor with the house that I bought 2 years ago. She wanted to know if she could help me with refinancing my home. I said no thank you, but she persisted in trying to sell me. That is fine. But I know she no longer works with this Realty Company and is with a local Mortgage company...but she used the Realty companies name. Sould I drop it, inform the Broker whom I know personally, or report her to Department of Financial Institutions? If I were the Broker I would probable like to know.
