Deerma T30w Returned More Damaged After Warranty Repair

I purchased a Deerma T30w cordless stick vacuum from Deerma Türkiye. The vacuum developed a problem in the tube section where it connects to the motorized head. The tube began flexing on its own and moving back and forth during use. Since the product was still under warranty, I sent it to the authorized service center. However, after the service process, the product was returned to me in a condition that was significantly worse than before.

During our communications, the authorized service center specifically told me that the tube would be replaced with a brand-new one. However, instead of replacing the tube, they apparently chose to simply put two screws into the existing tube and return it to me. Following this improper intervention, the metal section of the tube became severely damaged and cracked, and adhesive was also applied to it. Glue was applied around the tube's connection points, and the electrical wiring was also damaged and disconnected. The broken wire was then apparently reconnected and the assembly was closed again. In other words, the service center failed to keep its promise to replace the tube with a new one and instead left both the tube and the electrical components in an even more damaged and potentially unsafe condition.

As a result of this improper repair, the tube now moves much more than it did originally, and the inside of the tube is almost completely blocked because of the screws that were inserted. I am seriously concerned that continuing to use the vacuum in this condition could create a risk of motor failure as well as electrical safety issues. I do not accept receiving a product that I sent in under warranty in an even more defective and unusable condition because of careless and improper service intervention. I am also providing photographs of the tube in its current condition, which clearly show that the part has been rendered unusable following the service center's intervention.

I request that the tube and all damaged components be replaced free of charge with brand-new, fully functional parts, as was initially promised by the service center. I also request that I be provided with a clear written explanation of how this issue will be resolved and how the remainder of the service process will be handled.
