I received a short message from the post office saying that I haven't come to pick up the parcel yet, and asked me to call 298 1730. Is it a lie?

Said it was a post office. . . I'm responsible for telling you that the post office itself won't send you text messages at all, except that ems sometimes sends you text messages! Please pay attention to the number and content of the messages you receive. Generally, any courier company will sign the bill after delivering the courier and only let you pick it up. Even if the post office sends you a text message, it will never let you contact anyone, but directly tell you where to pick up the package.
