Arçelik 270560EBC Refrigerator Not Cooling And Making Loud Noise

"Dear Arçelik Official, The issue we have been dealing with since February 7 continues in a tragicomic manner. Due to both the email I wrote to customer service and my post on şikayetvar.com, since my last message, I have been constantly called and given information about the part replacement appointment, whether they came or not, showing a superficial interest. Whenever I tell each caller about my main issue and the need for the replacement of the cooler, the classic response is, "Believe me, we do not have the authority to make this decision." Let me get to the tragicomic part. Today, the technician (Mr. Abdullah, who is always attentive and concerned) who came for the appointment to replace the motherboard and rear heating pipes was unable to fix the issue because the transformer of the brand new motherboard from the factory arrived BROKEN! (photo attached). For the past two days, the plug has been unplugged to allow the ice in the deep freezer to melt, and the frozen products had to be given to others to prevent them from going to waste as usual. Now, a part order will be placed with the factory again, and we will wait once more. On top of our already dissatisfied situation, this adds to it, and I really can't reconcile these issues with a brand like Arçelik, and I'm at a loss for words. To make our voice heard and explain our problem to find a solution, I want to speak with someone who is truly authorized to make a decision on this matter, rather than customer service consultants who call me and repeat the same template sentences. I will not let go of this issue even after the necessary parts are replaced. Because I know for sure that the same fault will occur again at most by the summer months..."
