Hello, I don't know the person who signed for the package, and I asked my neighbors but they didn't receive the package. I have given the seller my personal tax number, personal information, and contact information. If I am not the one who signed for the package, it should be the courier or the seller who did not provide rigorous service. Isn't this the seller's responsibility? And the amount of this order is more than 1,000 euros, why can someone else sign for it?
