Credit protection statement is the same as fraud alert. Fraud alert has many aliases: victim’s statement, fraud alert statement, consumer statement.

I suggest you to check credit report immediately.

I don’t think that CSR knew what she was talking about.

There is fraud alerts and there is freezing a credit report but there is no such thing as a “credit protection statement”
Even if you had a fraud alert or had frozen your credit report, a company that you have an existing account with can still pull your reports.

You might call back and speak to a different CSR.
When asking for an increase, you should ask about a “guideline” credit limit increase with no hard pull
