Complaint Letter About Unsatisfactory Online Clothing Purchase

The letter clearly addresses all three bullet points with specific purchase details (receipt number, payment method, items), a detailed description of the collar, colour, and size problems, and a convincing reason for urgency, all in a consistently formal register with only a mildly abrupt closing demand.

Ideas are logically organised into paragraphs that each handle one bullet point, with cohesive devices such as 'Not only that but also', 'As for the trousers', and 'So, please' guiding the reader smoothly through the message.

The vocabulary is generally appropriate for a formal complaint, including items like 'round-neck collar', 'receipt number', and 'at your earliest convenience', though phrases such as 'decent summer dresses' and 'lodge a complaint to' show occasional imprecision.

A good range of sentence structures is used with mostly accurate control, including complex forms like relative and conditional clauses, despite a few minor slips such as awkward punctuation and slightly unnatural constructions.

All three points are covered with useful purchase identifiers, an exact description of the colour and size mismatch, and an event next week explaining the urgency. The replacement request and enquiry about returning the incorrect item make the desired action clear.

The letter moves logically from purchase details to the problem and then the requested solution. Repetition of the delivered product and the blue medium-sized sweater makes parts of the explanation unnecessarily repetitive.

Vocabulary is appropriate and sufficiently varied for a complaint, including “replacement” and “prompt attention.” Repeated use of “product,” “sweater,” and “ordered” limits flexibility, although the problem remains precisely understandable.

The response uses relative clauses, a since-clause, and passive forms with generally good accuracy. The comma after “so” in “so, I urgently require” is unnecessary, while the closing fragment “Looking forward to your response” is less grammatically complete than the surrounding formal sentences.
