Task Achievement & Content: Level 2. You cover the required complaint points: the wrong room, the unsuccessful request to change it, the faulty air conditioner, poor cleanliness, and a request for compensation. The purpose is clear in “I kindly ask you for a partial refund or a discount for future stay.” However, formal register is not fully consistent, particularly in the greeting and a few references such as “The girl who was working in front desk.” This meets Level 2, but not yet Level 2+, because the professional tone is not suitable throughout.

Organisation, Cohesion & Coherence: Level 2. The email has a clear overall order: introduction, room issue, air-conditioning issue, cleanliness issue, compensation request, and closing. Separate paragraphs help the reader follow your complaint. However, some links between ideas are awkward, for example “In additionally” and “Other problem was…,” so cohesion is still sometimes limited rather than consistently smooth.

Vocabulary Range & Control: Level 1+. You use some useful complaint vocabulary, including “standard room,” “partial refund,” “hygiene,” and “reputation.” However, several word choices are inaccurate or unnatural for a formal complaint, such as “accommodation time,” “technical air conditioner,” and “conformable.” There are also spelling slips, such as “sad” and “replay”; these are vocabulary/spelling issues, not grammar evidence. Vocabulary control is therefore close to Level 2 but is not consistently precise enough yet.

Grammar Range & Accuracy: Level 1+. You can communicate with simple past forms and some longer sentences, for example “When I booked the room… I was given a standard room.” However, basic grammar accuracy is inconsistent, especially with articles, plural forms, verb tense/agreement, and sentence structure: “no one come to fix it,” “these problem,” and “that is not possible” in a past-time account. These recurring basic-structure problems keep this aspect at Level 1+.
