Band 6+: How do most people respond to bad services?

Your pronunciation is very good. Aim to refine subtleties and intonation to further improve.

The answer is relevant to the question and provides a main point. However, it lacks further development and detail. Consider expanding on the different ways people complain (e.g., writing letters, contacting customer service, leaving online reviews, word-of-mouth). Also, explore other responses besides complaining, such as switching providers or simply accepting the poor service. The response could be expanded as it currently feels quite brief.

The answer is coherent and easy to follow. Minor improvement could be made by removing the unnecessary phrase "that the most common way that people use to." The response is fluent, with only a slight redundancy.

The vocabulary is adequate and appropriate for the task. More sophisticated vocabulary could be used to express the idea of complaining, such as "register a complaint" or "voice their dissatisfaction." The phrase "bad services" is a bit simplistic; consider using "substandard services" or "poor-quality services" for a more nuanced expression.

The grammar is mostly accurate. The phrasing "the most common way that people use to respond" is slightly awkward. The refined answer shows a more concise and grammatically correct way to express the same idea. The use of "either formally or informally" demonstrates good grammatical range.
