Monster Tulpar T7 26.1.5 Malfunctioning & Return Denied

On March 9, 2024, I received my Monster Tulpar T7 26.1.5 device, which I ordered from Hepsiburada.com. I couldn't even use the device consistently for a week. I had frequent shutdowns, freezing, and blue screen issues. In addition, there was backlight bleeding on the screen. Even in power mode, the battery could not survive longer than 30 minutes. Sometimes the device would shut down unexpectedly and restart itself, becoming trapped on the Windows launch screen. I utilized the device cautiously and exclusively through legitimate means. I never visited third-party websites or downloaded games; I solely used Steam, Xbox, Epic Games, and Riot. I never used external memory or comparable devices. I set up a return appointment to return the equipment before the deadline and was contacted by technical support. They said they will fix the problem. They accessed the gadget remotely and canceled my scheduled return appointment. Throughout the process, they stated the gadget was mended, but I continued to have trouble. I stated my intention to use my right to return the gadget. The item is a terrible disappointment and a total disaster! I demand an immediate refund and take action against the employees who hampered the process by canceling my appointment. This is a defective product that cannot be repaired. It's a service and product that don't measure up to Monster's standards. It's been a dreadful experience to have such problems with a device that I was so happy to get. I hope they authorize my return shortly. Otherwise, I'll escalate this to the Arbitration Committee.
