IELTS- letter of complaint: my dissatisfaction about the mobile phone

Dear Sir/ Madam,

I am writing to express my dissatisfaction about the mobile phone that I bought in your store.

I purchased a white Sony Ericcson Xperia10 last Wednesday, June 5. Before I paid for it, we had tested the unit and it seemed to function well. However, after three days of using, it became defective. With all its fantastic features and warranty, I never thought it could easily broke off. I am extremely disappointed with the product, and I never expected this to happen. Yesterday, I called your store and spoke with the shift manager. He told me to have it repaired. I am not satisfied with your product and service.

I would like you to replace the phone with a well-functioning one. I would like to receive the same type of unit and brand. Otherwise, I will be forced to report this to the department of government responsible for this problem.

You may contact me at 8304238 any moment. I look forward to hear from you soon.

Faithfully yours,

Miss Ican Diss

For this letter, a list of the defectiveness of the mobile phone would be needed. This way, a point is made that it is the phone itself and not something you, as the consumer, did. It would help to introduce yourself instead of jumping straight into issue, that way it doesn't seem as informal. I understand the point of the letter, but it would to provide information for the manufacturer to know what will fix the problem, such as a way to receive the new product or any other compensation they're willing to provide. The best way to make your point is to be respectful, which you somewhat did. Even emphasizing on the lack of service from the seller would help the case and help provide more insight into the situation. Other than that, minor word usage can be easily fixed and the letter can turn out better than before:) Good luck!
