Pam,
What a shame. I hope your neighbor did retrieve the package for you. This may be an inconvenience for your future deliveries. But for UPS deliveries and probably FedEx also, you can have them hold it at their depot. You can then pick up the packages in person at the depot. You can even prearrange to pick them up on a Saturday. Not sure how close the depot is to you. Mine is about 7 miles away. I've used this feature, whenever I get packages requiring a signature. I live alone and my dog can't sign for them, yet. She's good at chasing away squirrels, rabbits, cats and woodchucks, though.
