The number two most hated company in my pantheon of "Most Hated Companies" is FedEx.  In the eleven years that I have lived in the house, NOT ONCE has FedEx ever managed to deliver a package, parcel, or letter (regardless of service level) on time or correctly.  In fact, I no longer purchase from companies that only ship through this shitbag company.  Unfortunately, I don't always have a choice when I am expecting something really important -- like the final payout of vacation from my previous job.
