Formal complaint letter in French: the lesson
What does a formal complaint letter contain?
A lettre de réclamation is a short, factual and polite letter sent to a company when a product or a service has failed. The tone stays formal: use vous, skip jokes, and state what happened, what it cost you and what you expect.
Order of the blocks
- Your address, then the company’s address.
- Place and date: Lyon, le 4 avril.
- The subject line: Objet : réclamation, commande n° 4821.
- The greeting: Madame, Monsieur,
- Facts, request, deadline.
- The closing formula, then your signature.
How do you describe the facts?
Use the passé composé for events and the imparfait for the background: Le 12 mars, j’ai commandé un lave-linge. La livraison était prévue le 20 mars, mais le colis est arrivé le 2 avril avec la porte cassée. — On March 12 I ordered a washing machine. Delivery was planned for March 20, but the parcel arrived on April 2 with a broken door.
| Function | French | English |
|---|---|---|
| Purpose | Je me permets de vous écrire au sujet de… | I am writing to you about… |
| Fact | J’ai constaté que… | I noticed that… |
| Reminder | Malgré mes deux relances, je n’ai reçu aucune réponse. | Despite my two reminders, I got no reply. |
| Request | Je vous demande de me rembourser. | I ask you to refund me. |
| Deadline | dans un délai de quinze jours | within fifteen days |
| Consequence | À défaut, je saisirai le médiateur. | Failing that, I will go to the mediator. |
How do you ask without being rude?
Soften the request with the conditional or with souhaiter que + subjunctive: Je souhaiterais obtenir un échange. / Je souhaite que vous me remboursiez. After demander de and prier de, use an infinitive: Je vous prie de remplacer l’appareil.
Watch out, English speakers
Never write Cher Monsieur to an unknown reader: use Madame, Monsieur,. Do not translate “Sincerely” as Sincèrement. And demander que needs a subjunctive, so Je vous demande de rembourser is the safe pattern.
How do you end the letter?
The classic closing is one long sentence: Je vous prie d’agréer, Madame, Monsieur, l’expression de mes salutations distinguées. Add a short line before it if you wish: Dans l’attente de votre réponse,. The greeting is repeated inside the closing.
Good to know in France
For a serious dispute, people send a lettre recommandée avec accusé de réception, which proves the date the company received it. New goods carry a legal guarantee of conformity of at least two years, and companies must give consumers access to a free mediator.
Zoé’s tip
Write your request as one sentence with a date, such as avant le 30 avril. A letter with a clear deadline is much harder to ignore.
Key points to remember
- Open with Madame, Monsieur, and never with Cher when the reader is unknown.
- The subject line starts with Objet : and names the order number.
- Facts use the passé composé for events and the imparfait for the background.
- A request is softened by je souhaiterais or je vous prie de + infinitive.
- A deadline such as dans un délai de quinze jours makes the letter effective.
