Why did I change two people among a courier? Official website and SF APP couldn't find them, so the text message was sent. Could it be because I complained?

The change of personnel in the middle of express delivery may be due to the personnel adjustment during delivery. This may be due to some special circumstances, such as the courier's illness or resignation. In this case, the courier company may arrange other personnel to continue to complete the delivery task.

If you can't find the relevant information on the official website and SF APP of the courier company, but you receive a short message prompt, it is likely that your courier has arrived at the courier company where your destination is located and has arranged a dispatcher to deliver it.

Regarding your complaint, if your complaint is related to the dispatch service of the courier company, then the courier company may strengthen the dispatch management and supervision in this respect, which may lead to the occurrence of replacement. However, this is not necessarily because you complained about the courier company, but also for other reasons.

Generally speaking, if you receive a short message from the courier, you can wait for the courier to contact you to pick it up. If you have any questions or need more information, you can contact the customer service of the courier company for consultation.
