You recently bought a laptop from an online shop. When it arrived, it did not work properly.
Write a letter to the shop’s customer service manager. In your letter:
describe what you ordered and when
explain what is wrong with it
say what you would like the shop to do
Write at least 150 words. You do NOT need to write any addresses. Begin your letter as follows: Dear Sir or Madam,
Dear Sir or Madam,
I am writing to complain about a laptop I ordered from your website on 3 March, order number 48213, which was delivered last Friday.
The laptop looks undamaged, but it has two serious faults. The battery will not charge beyond 20%, even when it is left plugged in overnight, and the screen flickers whenever the brightness is turned up. I have followed the steps in the manual and updated the software, and neither problem has gone away. As I need the laptop for a course that starts next week, this is causing me real difficulty.
I would like you to replace it with a new one of the same model and to arrange for the faulty one to be collected at your expense. If a replacement cannot be delivered within seven days, I would prefer a full refund.
I have attached a copy of the receipt and two photographs of the screen. I look forward to hearing from you.
Yours faithfully,
Nadia Rahman
