Complete Body Sold gift certificates for cash then did not honor them. Bozeman Montana

I purchased five gift certificates totaling over $600 in Cash from Nina DeGidio Haarer dba Complete Body Works before she changed her business entity. She told me that they never expire. When I reached out to her to schedule my appointments, she said she would not honor them. She went onto Personality attack me for asking her to honor them. I thought she was a decent human, but turns out she is a crook who only looks out for herself. She then said she has a great reputation so go ahead and leave a review.  It is sad that people treat  people that way when they don’t think anyone else will know or believe it. It speaks to her true character.
