First of all, you need to know the meaning of taking a photo to sign for it, which means that no one signed for it at that time, and the courier took a photo of the waybill himself as proof of signing for it. Generally, it is sent to the company, and the doorman of the recipient is not found, and there is no receipt stamp. In principle, it is not allowed to sign for it. Express mail is usually with the doorman now. Of course, the courier company can complain, but the complaint is invalid and fruitless.
