Dear Sir/Madam,

I am writing to formally complain about a product I purchased from your store on 5th October 2025. The item, a wireless headset (Model X200), was advertised as brand new, but upon opening the package, I discovered that it was defective. The left earbud produces no sound, rendering the headset unusable.

I kindly request a full replacement of the product or a refund at your earliest convenience. I have attached a copy of the receipt and photographs showing the defect. Please let me know the procedure to return the faulty item and receive the replacement.

I hope you will address this matter promptly, as I have always trusted your brand for quality products. Thank you for your attention and I look forward to your swift response.

Yours faithfully,
[Your Name]
