During our meeting two days ago, the gentleman named Bu*** P***r, who introduced himself as the Amazon team leader, told me that if they did not call me by 16:00 on 01.07.2024, he would use his authority to create a solution and have the device removed from my address. On the same day, they sent me an e-mail because my phone was not registered in the system. He asked me to update my phone. However, my phone appears to be registered in the system.
