Refund Request for Faulty Robor Air 5 Bluetooth Earphones

Hello; I had to reiterate my complaint about the Robor Air5 wireless headphones that I purchased through the Vodafone Yanımda Application, which I had previously complained about. When I first received the product that I purchased from the web application on 19.09.2024, my complaint was that the left earphone was not working and the type-c port was defective. I was told by both Vodafone customer service and later by a call from Şikayet Var that I needed to send it to service, even though I did not agree with this because I did not buy the product by seeing, knowing, and touching it. Despite having the right to return it online, they ignored this and asked me to send it to service. I sent the product to service (it was September 22 or 23), and the product came back after about 10 days. I was able to use the product for about 1 month. However, again the left earphone started not working, and even though I charged it, it was showing low battery. I sent it to service again about 2 weeks ago. The product came back on Friday as repaired, and I charged it again, but it was showing half charge. I called the service, and they said charge it again, it should be fixed. I somehow used it with half charge, then again the left earphone did not work. And finally, today, even though I charged it, it was not charged at all. And it does not charge in any way. Vodafone is not standing behind the product, I am fed up with the product and I am requesting a refund. I was able to use the product for at most 1 month and sent it to service twice. I am in a victimized situation. If the problem is not going to be solved and if you cannot help, I will apply to the Consumer Arbitration Committee, just so you know. Have a nice day.
