Subject: Complaint Regarding Defective Smartphone Purchase

Dear Customer Service Team,

I am writing to express my dissatisfaction with the smartphone I purchased from your company two weeks ago. Unfortunately, the device has several serious issues that prevent it from functioning as advertised.

Firstly, the battery drains completely within a few hours, even when the phone is not in use. Secondly, the touchscreen often freezes, making it extremely difficult to perform basic tasks. In addition, some of the applications crash repeatedly, which makes the device unreliable for work or personal use.

These problems have had a significant impact on my daily life. I rely on my phone for communication, work emails, and online banking, and the current situation has caused me considerable inconvenience.

Given these issues, I kindly request either a full replacement of the smartphone or a complete refund of my purchase. I hope this matter can be resolved promptly.

Thank you for your attention to this issue. I look forward to your response.

Sincerely,

[Your Name]
