It greatly depends on the country. In many countries, couriers do call the receiver in advance (Some will send SMS or email). But if you missed the call, they probably will not call again as they have a huge number of parcels to pick-up and deliver daily.
Once you call them back, they will request the detailed shipping information of your package. So make sure you have it at hand.
In many countries, couriers will contact the shipper or receiver to arrange the time frame before parcel pick-up and delivery.
However, it depends sometimes. Some couriers cannot schedule the delivery manually. To keep your glasses safe and sound, please pick up your parcel as soon as possible. Otherwise, it may be returned to the warehouse after the collection time.
Nothing to worry about! We will contact our courier to locate where your parcel is as soon as possible. If the package is missing in transit, we will help you with the replacement or refund. Please contact our customer service via email at email@example.com.
