Why did the courier send a message saying that it was there, but he went to the courier's place to pick it up? People say there is no such thing.

Check the express delivery number, sue in online customer service or telephone customer service, look at online information records, and communicate with customer service first. Maybe the courier took it out, maybe it wasn't handled locally, or maybe it gave you an error message. In short, it is better to contact customer service first and let them find the record of express delivery, so as not to make a trip in vain. If you still can't verify it, then upgrade immediately, make a complaint call, let them pay attention internally and find it for you with greater strength.
