Amazon Ignores Defective Bose QuietComfort Earbuds Replacement Request

The left earbud of the Bose QuietComfort Earbuds - Wireless Noise Cancelling Headphones, White—purchased under difficult financial circumstances by my son B**** O**** from Amazon.com TR for my use—has not been working for a long time. Despite searching for the contact phone numbers that are legally required to be listed on the site, I could not find a way to reach them. Even though I attempted to contact the relevant company via email as a last resort, I have received no response to my emailed petition so far. The corresponding invoice copy is attached. Although the product invoice is dated June 21, 2024, the shipment arrived 2 days later, and despite reporting the issue to both Amazon.com TR and the manufacturer Bose, I have received no reply. I demand a return or replacement of the product.
