If Kemper had your data

1. Look for Kemper’s own notice or letter: it should say what of yours was involved. Keep it.
2. Call your bank on the number printed on your card (never one from a message), check recent payments and ask for a new card.
3. Expect scams that use your details: calls, texts or emails pretending to be Kemper, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
