This is a typical scam. You can refuse them if they have delivered the goods. At the same time, I suggest you handle it carefully to prevent being cheated. If you are cheated, I suggest you call the police.
At work, the police found that some people spread the message of "free delivery" of Kweichow Moutai on APP platforms such as Tik Tok and A Auto, and tricked people who didn't know the truth into calling back, thus defrauding suspicious clues of "courier fee". After careful study, dehui city Public Security Bureau determined that this was one of the ways of committing crimes by telecommunication network fraud criminal gangs. The main leaders of dehui city Public Security Bureau immediately deployed elite police to set up a task force to judge the identity information of the people involved. After the close cooperation and continuous operations of several departments, the police of the task force found that the gang had a clear organizational structure and a clear division of labor. After the gang members released the false information of "free delivery" of Kweichow Moutai on various platforms, they tricked the masses into drawing lottery and reserved telephone numbers, and then designated specially trained operators to call back the reserved numbers. They gradually induced the victims to fall into the trap according to the specially formulated speech content, and illegally obtained the "courier fee" 198 yuan for each transaction. In fact, the "free delivery" is not pure Moutai, but ordinary liquor worth several yuan per bottle. On August 20th, dehui city Public Security Bureau took unified action to arrest the suspects involved, and * * * arrested 45 gang members.
