Write a letter to the shop or company which supplied the equipment. In your letter

• explain how this problem is affecting your work
• say what you want the shop or company to do

You do NOT need to write any addresses.

Begin your letter as follows:

Dear Sir or Madam,

Student answer (Band 7.5)

Dear Sir or Madam,

I am writing in connection with a problem that I have encountered with a microphone that belongs to the Sony company. It is 15 cm long and weighs around 280 grams. It is worth 800 dollars in Jet black colour.

The major issue I am facing is voice sounds muffled, unclear, and low. Moreover, it picks up unnecessary background noise such as fans and people talking nearby.

As I work from home, these issues affect my overall productivity and efficiency while talking to clients online. I was not able to accomplish my task on time, and sometimes, due to these issues, the call disconnected or wasted the time of both parties.

I would like to get a repair or replacement as soon as possible, as promised. Please send a mechanic to check this device or offer to replace it at my home.

I hope you will address this and maintain customer satisfaction service.

Yours sincerely,

Shilpa Shilpa

Task Achievement / Task Response — Band 8.0

The letter successfully addresses all three bullet points required by the prompt. You clearly describe the microphone's issues, explain the negative impact on your professional productivity, and state your desired outcome (repair or replacement). The tone is appropriate for a formal complaint letter. To reach a higher band, you could provide more specific details, such as the date of purchase or the order reference number, to make the request more realistic and professional. Overall, the response is well-focused and fulfills the requirements of the task effectively.

Coherence and Cohesion — Band 7.5

The letter is logically organized, with each paragraph focusing on a specific aspect of the prompt. The progression of ideas is clear, moving from the description of the item to the problem, the impact, and finally the requested action. You use some cohesive devices like 'Moreover' and 'as soon as possible' to link ideas. To improve, you could use a wider variety of linking words and ensure that the transition between the description of the microphone and the problem is smoother, perhaps by using a more formal opening sentence for the second paragraph.

Lexical Resource — Band 7.0

You demonstrate an adequate range of vocabulary to communicate your message clearly. Phrases like 'encountered a problem' and 'overall productivity' are well-chosen. However, there are some minor inaccuracies in collocation and word choice, such as 'maintain customer satisfaction service' which is slightly unnatural. Using more precise technical terms or professional business language would enhance the quality of your writing. The vocabulary is sufficient for the task, but further development of topic-specific collocations would help you achieve a higher score.

Grammatical Range and Accuracy — Band 7.0

You use a mix of simple and complex sentence structures, which is appropriate for this task. Most sentences are clear and easy to follow. There are some minor grammatical slips, such as 'in Jet black colour' (should be 'in a jet-black color') and 'the call disconnected' (should be 'calls have been disconnected'). Despite these occasional errors, your meaning is never obscured. To improve, try to incorporate more varied complex sentence structures, such as using conditional clauses (e.g., 'If this issue is not resolved, I will be forced to...').
