Final answer:
Jasmine should cancel her credit card, contact the bank, confront her roommate, and possibly report the incident to the police to safeguard her financial security and address the unauthorized credit card use.
Step-by-step explanation:
If Jasmine's roommate used her credit card without permission, Jasmine should take several steps to protect her financial security and address the situation. Firstly, she should cancel the credit card and contact the bank to report the unauthorized use. By doing so, she can prevent further unauthorized charges and potentially have any fraudulent charges reversed. Secondly, Jasmine should confront her roommate and demand an explanation. It's important to communicate that using someone else's credit card without permission is illegal and a violation of trust. Lastly, while it may seem severe, reporting the incident to the police is a step she can consider, especially if the roommate does not cooperate or if there is a significant amount of money involved. It's critical to establish a clear record of the incident in case of further fraud or legal issues.
Jasmine should also take additional steps, such as monitoring her credit history, to check for any red flags that suggest her identity has been compromised. Understanding why personal information is being collected and how it is used is crucial for protecting one's identity and financial accounts.
