1) Linda waits for about 2 weeks and she is at home now. 

Postman deliver the package and she signs her signature on it. 

2) Linda is not at home or office during delivery. Postman leave a absence note. 

Linda knows whehter the package arrives near local post office. 

Linda get the items on the second trial of Postman.

3) if Linda does not get noticed or wondering where her package after 20 days from shipping. 

You message me via e-mail first and  call local Post Office by mentioning your tracking number.
