Dear Mr. Henderson,
I am writing to express my dissatisfaction with a high-end Zenith noise-cancelling headset I purchased from your branch on 12 October. Despite the premium price, the device has failed to function correctly since I unboxed it.
The left earcup produces a persistent, high-pitched static noise whenever the Bluetooth connection is active. Furthermore, the battery fails to hold a charge for more than thirty minutes, which is entirely unacceptable for a product marketed as having a forty-hour lifespan. I have attempted to reset the device according to the manual, yet the issues persist.
Given that the item is clearly faulty, I would like to request a full refund or an immediate replacement with a brand-new, tested unit. I have enclosed a copy of my receipt and the original warranty documentation for your reference.
Please confirm in writing that you are prepared to process this return and provide instructions on how to handle the shipment back to your store. I trust this matter will be resolved promptly.
Yours faithfully,
Jonathan Sterling
