What examiners want to see in a TELC B2 complaint letter
A strong complaint letter is not aggressive. It is precise, polite, and solution-oriented. Examiners look at whether you explain the situation clearly, establish the context properly, formulate your request in a direct way, and maintain a formal tone throughout the letter.
The basic structure is almost always the same:
- State the reason: What happened?
- Describe the problem clearly: What exactly was wrong?
- Explain the consequences: Why does it matter?
- Demand a solution: What do you expect now?
- Close politely: Ask for a deadline or a reply.

How to turn any new topic into a letter quickly
Many learners lose time because they try to invent a completely new structure for every topic. That is not necessary. Use this short formula instead:
- Sentence 1: establish the context
- Sentence 2: state the main problem
- Sentence 3: explain the consequence or disadvantage
- Sentence 4: demand a concrete solution
- Sentence 5: close politely
If you automate this formula, you can structure almost any topic within a few minutes.
The most common mistakes in complaint letters
- writing too emotionally instead of arguing in a factual way
- describing the problem too vaguely
- not formulating a clear request
- using informal language like in WhatsApp messages
- forgetting a polite closing
- adding too many unnecessary details without focusing on the solution
