Amazon and The Seller Refuse RTX 4070 Ti SUPER Warranty Replacement

I purchased a GIGABYTE GeForce RTX 4070 Ti SUPER WINDFORCE OC 16G graphics card on Amazon marketplace (Order No: 404-3722650-2086724, account holder: Cengiz Ş***) on 4 November 2024 from the seller DFS Bilgisayar. In October 2026 the graphics card became completely unusable due to a hardware failure and stopped providing any display output. On 9 October 2026 the defect was officially confirmed by an authorized service report issued in my name, and the product is clearly within the statutory 2‑year warranty period. Despite this clear defect, DFS Bilgisayar accepted the fault but unilaterally decided only on a refund and explicitly refused to provide a replacement. I invoked my statutory right under Turkish Consumer Law No. 6502, Article 11, and clearly requested replacement with a brand new, identical or superior model without any additional cost to me. Nevertheless, DFS Bilgisayar insisted that they would only refund the original purchase price, which has been severely eroded by inflation and is no longer sufficient to buy an equivalent graphics card today. Amazon Turkey customer service was also informed of the situation, including the authorized service report and the seller’s refusal, yet they stated that “the seller is DFS Bilgisayar, we cannot do anything” and refused to take responsibility as the marketplace operator. In the following days, all my communications with both DFS Bilgisayar and Amazon Turkey support up to mid‑October 2026 resulted in the same answer: they insist on a refund only and refuse to fulfill my statutory right to replacement with an equivalent or superior product. As a result, I have filed an official complaint with the Consumer Arbitration Committee under Sakarya THH Application No. 2026/0098.8851. I consider both DFS Bilgisayar and Amazon Turkey jointly responsible: DFS Bilgisayar for not honoring my statutory warranty rights as the seller, and Amazon Turkey for failing to enforce and respect consumer protection rules on its platform, despite being fully informed of the situation and the legal basis of my request. I hereby request that my statutory right under Law No. 6502, Article 11, be fulfilled without any further delay. I demand immediate replacement of my defective GIGABYTE GeForce RTX 4070 Ti SUPER WINDFORCE OC 16G graphics card with a brand new identical or superior model, such as a GIGABYTE RTX 4070 Ti SUPER 16GB or an RTX 4080 / 4080 SUPER, at no additional cost to me, instead of a monetary refund that does not allow me to obtain an equivalent product in today’s market conditions. I ask Amazon Turkey and DFS Bilgisayar to urgently comply with their legal obligations and to inform me in writing of the replacement process.
