Media Markt sales manager advised me to make an additional protection package for an additional fee, I accepted that your device's own warranty and that you have +3 years for 5 years total protection package for you have protection under warranty, insurance and insurance. 4. He gave his first failure in 06.02.2023 of the year. I created the fault record by calling Media Markt (failure: in-panel dusting) customer service WhatsApp line (Cardif Insurance Damage Management) product image invoice information, I sent it to a full address. Antalya (Necmi electric) took the product and delivered it repaired within 20 working days. In the following months, on 10.10.2023, my television failed again (in-panel dusting and factory Mode), so I called the Media Markt (0850 222 15 00) line again, I created a fault record, I sent the necessary documents (Cardif Insurance Damage Management) in the same way within 3 working days, Necmi electrical personnel took my device for repair again and delivered it within 15 working days. On 04.12.2023, he gave a malfunction again (the panel LED lighting problem does not work in the middle of the TV, the dark sides in the middle of the screen are normal, more than 20 pixels and again dusting again) On 05.12.2023, I called Media Markt at 11:00 at 11:00, they asked me to send the invoice of my product to WhatsApp lines (Cardif Insurance Damage Management), the image of the defective state of my product and my open address, and I sent it. Customer service stated that the product will be received within 24 hours. I also wrote a message to learn the latest situation about the service at 17:53 in the evening at 17:53, the insurance company gave feedback as it is in the repair process. Today, when I called Media Markt customer service again on 11.12.2023 and asked why it was not taken my product, you did not open a record at 08.12.2023, they made a speech saying that your guarantee was over on 08.12.2023, as a result of the customer service was harsh to me, we talked to me, I asked them to investigate my audio recording that we could not be able to speak at 11:00 on 05.12.2023, they said they said that they looked at the messages I sent on WhatsApp, you sent yes, but they said that they said that they would not repair my television because they did not open my customer service registration, in this case, I am a victim I request.
