Audio Malfunction Of Philips 55OLED708 Ambilight

I bought a new Philips OLED TV that turned out to be broken, and I've been waiting a really long time for a response. We purchased the Philips 55OLED708 TV model on October 8, 2023, at the Ankamall Teknosa store. Right after the setup on October 10th, we let "Ozturk Elektronik Ankara Regional Authorized Service" know about the issue. The technician who did the installation gave us this information. They said they would assess the situation. Four days later, on October 14, 2023, someone from the authorized service came to our house and noticed an issue with the sound on the TV. They said they told the headquarters about the problem and promised to follow up with me. I waited for a long time, but nobody responded to me. I made a few phone calls and was told that they sent an email to the main office, but they haven't gotten back to me. They suggested that I reach out to the main office myself. When I got in touch with headquarters, they told me that they had escalated the issue, which caused a delay in finding a solution. I bought a new TV, but I'm still waiting for it to be fixed because it was delivered broken. Also, if it takes this long for a new device to fix problems, I'm curious about what might happen if another issue comes up. Also, why can't I get any updates or calls about the faulty brand-new product? All they keep telling me is to wait again and again. The only phone call I got during this time was when I reached out to the main office and someone from a local number called to ask about the problem. If someone asks for advice on purchasing a Philips TV, I would advise against it based on my own experience. I spent a lot of money, my old TV is broken, and I haven't had a working TV at home for 20 days. But I still haven't gotten a simple apology for the trouble caused by the delay. Based on Article 4 of Law No. 4077, I want to say that I will do everything I can to fight for my rights.
