Yes. For your account security, you are required to respond to a fraud alert. This allows Advantis to either take immediate action to protect your account (if the charge was indeed fraudulent) or make your account available for additional charges (if the transaction was authorized). When our fraud monitoring service detects a suspicious transaction they may block your card immediately for your protection. Rest assured, shortly after you respond to a fraud alert and confirm that you authorized the transaction in question, your card will be restored.
