The best I ever had was the mob that later became Yodel, were they called Parcel delivery service (PDS)?
I bought a USD front end from a guy in Lincs for my stepsons bike I was building. The guy was also selling other large lumps of the same bike, engine and rear swingarm and wheel. The company managed to deliver all three packages to the wrong addresses, my front end was in Southampton, the rear end was delivered to me and some poor unfortunate in Norfolk got an engine when he was expecting a rear end. Took two months to sort out the mess with the lying bastids making up all kinds of tales of who's fault it was and "yes sir, your package has been retrieved and is on way to you" stories. So Yodels off my list.
