Dear Customer Service Team,

My name is [Your Name], and I purchased a television from your store on [Purchase Date]. Unfortunately, when I got home and set it up, I discovered that it did not work properly. The screen frequently flickers, and the sound cuts out intermittently, making it nearly impossible to enjoy any programming.

I immediately contacted your customer service hotline on [Date of Call], but despite my efforts, I have yet to receive any assistance regarding this matter. I believe that as a customer, I deserve a functional product and prompt support when issues arise.

I kindly request that you either arrange for a technician to repair the TV at my home or provide me with a replacement unit. I appreciate your attention to this matter and look forward to a swift resolution.

Thank you for your assistance.

Sincerely,
[Your Name]
