Something wrong with how your data was handled?
Tell us and the privacy/grievance team must respond. Complaints made from your signed-in session are tracked under your account with a reference number, so nothing gets lost in an inbox. You can also write to (operator grievance contact — configured under CMS → Privacy).
[STATUS: The complaint intake/tracking below is implemented in code. The designated grievance officer and the response timeline applied by the operator are an organizational decision; this site does not claim a specific officer has been appointed until configured — see CMS privacy settings.]
Sign in to file and track a privacy complaint (this keeps your complaint tied to the account it concerns, which is how we confirm it's really about your data).
Without an account you can still email the operator address above; please include any reference you were given.
