Band 9 Model Answer

📝 Annotated

Dear Sir/Madam,

I am writing to complain about a problem with a pair of earbuds that I recently purchased from your online store, which unfortunately do not work properly.

The product I bought was a pair of wireless Bluetooth earbuds (Model X200). It was delivered on 25th March and appeared to be in good condition when I received it. My invoice number is 009345XY3467.

However, when I tried to use them, the earbuds did not turn on despite being fully charged. I followed all the instructions provided in the manual, but the issue still remains. This has caused considerable inconvenience.

As a working professional, I rely on these earbuds for my daily tasks and cannot afford further delays. Therefore, I would appreciate it if you could either replace the product with a functioning one or issue a full refund at the earliest.

I look forward to your prompt response.

Yours faithfully,
Vishal Modi

Watch Out

Common IELTS Mistakes to Avoid

❌ Writing "Myself Mohan" — this is incorrect and informal in formal English

❌ Using informal tone: "Hey," "Hi bro," or casual greetings

❌ Missing a clear request — never forget to ask for a refund or replacement

❌ Overly emotional or aggressive writing — IELTS requires professional composure

⚠️ IELTS examiners look for professional tone + clarity — not emotion or drama
