I received a short message saying that your goods and gifts have been sent out. I received a parcel today and asked me to pay several hundred dollars.

There will be many such sudden moments in the real society. When you encounter this problem, you must first calm down. Think about it. How can you get a package if you didn't order it online? Someone else must have sent it to you. If someone else sent it to you, if a friend sent it to you, I will definitely inform you in advance. Even as a gift. Have you ever seen someone give gifts to others and ask them to pay? So this must be a scam. The usual trick of a liar.
