Reporting a scam in France

First hour, in order

Call your bank. Call your bank, then use the national card-opposition line if a card is involved.
Stop paying. No fee, tax or "release payment" ever unlocks money that does not exist.
Screenshot everything before you delete an app, block a number or close an account.
Then report using the routes below. Reporting is slower than the bank call, and less urgent — but it is what produces enforcement.

France’s public cyber-assistance service is Cybermalveillance.gouv.fr, which diagnoses the problem and routes you. For investment scams, check the AMF blacklists before doing anything else.

What not to do

Do not pay anyone to recover your money. No legitimate service charges an up-front fee to get stolen funds back, and people who have just been scammed are the primary market for recovery scams.
Do not use contact details the scammer gave you — not the phone number, not the "support" chat, not a link in a message. Look the agency up yourself.
Do not delete the evidence. Apps, chats, wallet addresses and transaction IDs are what make a report actionable.
Do not send one more payment. This is where most of the largest losses happen.
