I order a LOT of stuff from MyProtein.co.uk, who use Yodel to deliver.
Well, 'deliver' is maybe too grand a word for what Yodel do. I mean, they call themselves a delivery company, but I'm not so sure.
They've screwed up, in some unique and unfathomable way, EVERY order they've attempted to deliver over the last year. They've even been supposed to collect parcels from me, and have failed spectacularly at that, too.
If I ever need to send something, i'm not going to use Yodel. Honestly, it would be more effective and reliable to simply fire all your parcels up into the air with some kind of canon, and hope that a freak storm would blow them in the general direction of their intended recipients.
