Complaining and Apologizing — English Bac STM

This communicative function turns up in the Bac STM English paper's dialogue-completion and short writing tasks (coefficient 2). A damaged parcel, poor service, a missed appointment: knowing how to complain without aggression and how to apologize sincerely are two mirror-image functions, tested together because each answers the other.

Dans le programme du Bac STM

English carries a coefficient of 2 in the Bac Sciences et Technologies Mécaniques (STM) stream. The core subjects are Mathematics and Engineering Sciences (coefficient 7 each), then Physics-Chemistry (coefficient 5). English and Philosophy (coefficient 2) form the margin where candidate rankings and honours are settled. Mastering the structure of a piece of writing matters more here than memorising it.

À l'épreuve

Three parts: Reading Comprehension, Language, and Writing (about 180 words). Reading technical drawings and function diagrams builds the same skill an essay needs: breaking an argument into parts and rebuilding it as a coherent plan.

Objectifs d'apprentissage

  • Produce this function at the right register in a dialogue-completion task on the Bac STM English paper (coefficient 2)
  • Make a polite but firm complaint: I'm afraid I have a complaint to make / I'm not satisfied with…
  • Structure a formal letter of complaint: subject, facts, damage, request for redress
  • Apologize at the right register: I do apologize / I'm terribly sorry for the inconvenience
  • Distinguish a constructive complaint (which proposes a solution) from a mere criticism

Notions clés

Complaining politely

I'm afraid I have a complaint to make / I'm writing to express my dissatisfaction with… / I'm not satisfied with… The register stays polite even when the reason is legitimate: describe the facts before judging.

The formal letter of complaint

Typical structure: (1) the subject of the letter, (2) precise, dated facts, (3) the damage suffered, (4) a request for redress (refund, replacement, apology) and (5) a firm but courteous closing (I look forward to a prompt resolution).

Apologizing

I do apologize for… / I'm terribly / really sorry for the inconvenience / Please accept my apologies. A full apology acknowledges the problem, takes responsibility for it and, where possible, offers redress.

Erreurs fréquentes

1

Writing a letter of complaint in an aggressive tone (You never…!): the expected formal register stays firm but courteous, even with real dissatisfaction.

2

Leaving out the request for redress at the end of the letter: a complaint with no precise request (refund, replacement) looks incomplete to the examiner.

3

Confusing I'm sorry (an apology or sympathy, depending on context) with I apologize (a formal apology only): “I'm sorry for your loss” is sympathy, not an apology.

Exemple corrigé

Énoncé

Write the opening sentence of a formal letter of complaint about a parcel that arrived damaged.

Correction

Identify the register. A formal letter of complaint needs a direct but polite opening, with no over-familiar greeting.
Name the subject clearly. State the reason for the letter (the damaged parcel) in the first sentence rather than circling the topic.
Result. “I am writing to express my dissatisfaction with a parcel I received on 12 March, which arrived severely damaged.”

Questions fréquentes

What must a formal letter of complaint always contain?

A clear statement of the subject, the precise and dated facts, the inconvenience or damage suffered, and an explicit request for redress (refund, replacement, apology) — plus a firm but courteous closing.

Is “I'm sorry” always an apology?

No: “I'm sorry” can express sympathy rather than apology (“I'm sorry to hear that”). For a genuine apology in a formal context, prefer “I apologize” or “Please accept my apologies”.

How do I keep a complaint firm without sounding rude?

State facts, not accusations (“the parcel arrived damaged”, not “you destroyed my parcel”), use modal softeners (I'm afraid, I would appreciate), and end with a clear, reasonable request rather than a threat.

English is far from my mechanical specialism — how do I approach it?

Treat it as a system with inputs and outputs: the input is a prompt, the processing is analysis then discussion, the output is a conclusion that settles the question. Learn that flow, apply it to the 31 chapters with two examples each, and one weekly session is enough to raise the mark.

Why learn a spoken function for a written Bac STM exam?

Because it is tested in writing: dialogue-completion tasks ask for exactly these phrases at the right level of politeness. Keeping two or three set expressions per function, sorted by register, covers the task reliably.
