QCY Rejected Legal Withdrawal and Refund for Defective T13 Pro Earbuds

I returned my QCY T13 Pro earbuds—which I took delivery of on June 10, 2026—under the statutory 14-day "right of withdrawal" outlined in Article 48 of Consumer Protection Law No. 6502, as well as under the "defective goods" classification governed by Articles 8 and 11 of the same law. However, after the product arrived at the technical service center, my return was unjustifiably rejected without any concrete justification, accompanied merely by the claims that "no manufacturing defect was found."

The product exhibits clear defects that the service center overlooked or ignored during brief testing: momentary signal drops and sync errors occur between the left and right earbuds; phantom touches (Ghost Touch) trigger spontaneously on the touch panel, forcing me to disable touch controls entirely; the battery life—advertised at 10.5 hours with ANC off—measured only 8 hours and 53 minutes at 50%–60% volume, failing to meet promised technical specifications; and noticeable background noise ("hissing") and crackling occur on certain audio tracks (a clear hardware fault). The product was tested after performing factory resets, yet the issues persisted. Delivered complete with its original box and all accessories, this unit's defects reflect chronic, structural instabilities widely reported by other users of the same model.

As a customer, I have been mistreated, and an attempt is being made to ship a defective product back to me. I demand a full refund of my purchase price. Otherwise, I hereby declare that I will immediately file a formal claim with the Consumer Arbitration Committee using all the technical documentation, screenshots, and logs I have prepared.
