Hepsijet Sent Wrong TCL AC 9000 BTU - Order Lost In Transfer

On November 17, 2025, I purchased a 9,000 BTU TCL air conditioner from the seller Teknofish via Hepsiburada and the product was delivered to me on November 19, 2025. However, instead of the 9,000 BTU air conditioner I ordered, a 15,000 BTU air conditioner was sent. I immediately contacted the company and we started the exchange process. Hepsijet XL cargo picked up the product from me on November 20, 2025, but as of today, December 2, 2025, the shipment still appears to be in transfer and the process has not progressed in any way. During this time I wrote to Hepsiburada customer service countless times and requested to be called back four times, but no one called me. The seller Teknofish has not taken care of the process at all, Hepsiburada has not provided a solution, and Hepsijet cargo cannot be reached. Although 17 days have passed since the product was purchased from me, no one is asking where this product is or what stage the process is in; I feel that only I am following the issue. At this point, the product is effectively lost, the company is indifferent, Hepsiburada is not resolving the situation, and I have neither the product nor my money, even though I paid an amount equivalent to a minimum wage. I feel victimized, my time has been wasted, and I have been psychologically worn out because I worried about the product every day, constantly tried to reach the parties, and still could not get any concrete result and even started to worry about being scammed. I request that the correct 9,000 BTU TCL air conditioner I originally ordered be urgently sent to me without any additional cost and that an apology compensation be provided for the material and moral damage I suffered, including my wasted time, my ongoing anxiety during this period, and the stress and psychological wear I experienced due to the lack of any solution.
