Then it should be covered under the Visa network policies.
Tell her to go into a branch and speak to one of the people at a desk. They deal with this stuff every day.
Have her list out what the purchases were and why she could not have bought them.
Honestly, this is usually not a big deal. Tell your daughter to be calm, explain things, and listen to their answers. For this amount they may ask for a police report. That could get sketchy if she knows who did it and doesnt want them arrested. $2k is grand larceny in most places.
Thanks I appreciate it
