The thing with couriers, like the Royal mail, they handle tens of thousands of items each day, some are gonna get lost or damaged.
For every one that is lost or damaged, there are a thousand more that aren't, but you only get to hear about the ones that are damaged or mis-delivered.
Yodel are or were DHL.
I bought a cab from a guy on here a couple of years ago. He lived in Scotland and shipped it without a box or any packaging, just in its cover. He just stuck the label on and gave it to the courier (DHL), it got as far as Lichfield which is just up the road from me, before the cab and the label became separated from one another.
It took just a couple of phone calls from me to track the cab down, it was tracked to Lichfield luckily, so I knew it was there, I just described what it was and they found it. They were extremely helpful.
