Defective Order

I wish I had read the reviews before purchasing, I think I just trusted the brand, which was my mistake. I ordered two iphone 15 units online, which were delivbered on Thursday 16 april 2026. upon opening the first device, on friday 17 April 2026, I found that it had a software defect, the phone is stuck in some sort of recovery/update loop and is completly unusable. Since discovering the fault, I have attempted to resolve this through every available channel with no success: I have been unable to reach anyone via general customer care lines. The "TOBI" chat assistant has provided no resolution. An email I sent to customer care on 17 April 2026 has not been answered yet. On Saturday, 18 April 2026, I finally managed to speak with an agent at 082135, who informed me she could not assist and directed me to call *** on Monday. I am extremely disappointed by the lack of support, particularly given the premium nature of these devices. If i'm not mistaken there is a 7 day return policy, but at this rate im doubting this complaint will reach someone on time. I am requesting an immediate replacement for the defective unit, not a repair. The second phone remains unopened and in its original sealed packaging.
