You are only affected if you had an account or an order with this organisation.
What you can do
- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- Watch your statements. On any unknown debit, block the card and request a refund — French law (art. L133-18) entitles you to it.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
