Delivery companies make package collections throughout the day and typically do not provide a specific collection time. If you can wait at home, couriers generally operate collection windows from 8am to 6pm.
If the courier arrives when you're not home, they may leave a calling card with instructions. Contact Parcel Monkey's customer support team to rebook a collection slot if needed. Note that Parcel Monkey itself doesn't perform collections - the service provider does.
Alternative options:
Book collection from a work address
Arrange for someone you trust to receive the package at their address
Use drop-off services such as DHL eCommerce or other available options
Talk to the Parcel Monkey team about orders, customs or other general enquiries.
