All my points stolen in store!!!

How how! I am in WI and just received a receipt from a store in Indiana. Someone used all of my points down to the penny. I called the store and they said the persons id matched my name and dob when I asked about them checking. How?!

Update for some questions. The cops by me said they probably got into my ulta account and showed a random id off their phone if anything. They stole all $600 worth of my points but the store said they have good footage. I want to see her so bad!
