Is it true that Guizhou Post took the initiative to call?

Guizhou Post's voluntary phone call is generally false. You can further confirm the following, and beware of fraud.

In the past, someone reported that they had received such a phone call reminding them that there was a parcel at the post office. However, in general, small parcels were delivered directly to the door by the post office, and large parcels were sent to the recipient's hand, so that the recipient could pick them up at the fixed post office outlets. Only when the parcel address was not detailed, would the recipient be notified manually.

Therefore, the police suggest not to trust the so-called parcel call, which may be a scam such as defrauding the telephone bill.
