If IMA Diligence Services had your data

  1. Look for IMA Diligence Services, LLC’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. An ID number cannot be changed, so lock it: a credit freeze or fraud alert in the US, a credit warning (kreditadvarsel) on borger.dk in Denmark, Cifas protective registration in the UK.
  4. Check your health insurer’s statements for treatment you never had.
  5. Expect scams that use your details: calls, texts or emails pretending to be IMA Diligence Services, LLC, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.

One email to confirm first. We use your address only for this alert, and one click deletes it.
