Grundig Three Times Faulty Product Delivery! HS7034 Hair Straightener Came Wrong

This is the second complaint I have written about this product. This time, the issue is entirely related to the problem I have been experiencing with Arçelik's customer representative since 11/23/2023. The problem has gotten completely out of hand. The customer representative who called me was understandably tense because it was the fourth time they were sending a straightener, and they wanted to resolve the issue. I also wanted my problem to be resolved, and I was tense. The representative opened the straightener with my approval and, upon testing, said that the same malfunction was present, thus suggesting a refund. The conversation was not focused on customer satisfaction and resolution but rather on the problem itself because the representative did not want to deal with it anymore. I mentioned that the amount to be refunded (the initial purchase price) was not enough to buy a new straightener since the refund amount was 378 TL, while the current price of the straightener was 1275 TL. According to the customer representative, the solution was to use the straightener by pressing the middle part with my hand. While saying this, they continued to interrupt me aggressively, and I snapped at them to stop interrupting me, leading to a mutual argument. Neither the customer representative nor I were the cause of this issue. The faulty product caused both their employees and customers to become tense. My grievance was not addressed under the guise of a refund or product replacement. On top of that, while the customer representative continued to snap, they sarcastically said, "These products are like this, you keep sending them, and we keep dealing with them," and continued to give mocking responses. Finally, after our mutual argument, they listed their responses without taking a breath and hung up the phone while continuing to shout "have a good day." As a customer experiencing this grievance, I do not think a mutual argument is appropriate. I condemn the company and the customer representative who contacted me. A customer representative should focus on resolving the issue, not covering it up. Saying "I tried to resolve the issue, my tone was quite good (not realizing that trying to hang up the phone and giving sarcastic responses was not appropriate)" and implying that "there was no one worth it on the other end" does not reflect proper work ethics or mental health and is inappropriate. Should I be eternally grateful for the representative doing their job even though my problem was not resolved?
