Bad reputation for the company. Even if they are out of work baseball pitchers, they need to be trained before setting out. Unless you have a doorbell cam or a perimeter cam that can be a witness to it else you have no case against their words.I agree. I think delivery companies have had to struggle to meet demands. Maybe they hired untrained delivery workers? Perhaps they hired out of work baseball pitchers?
Over here, couriers will text or call before they arrive and if there's no one home, we have an option whether tp leave at doorstep or reschedule for another delivery.
Usually if we are not no home, we'll ask them to leave outside the house and some of them are very good and hide the parcel well and they'll take a photo and send it to us to show that the parcel is delivered.
