^"Amazon is facing mounting consumer backlash over its use of delivery company Yodel, with shoppers complaining of missing and damaged goods and orders that never turn up.
In the past week alone more than 100 people have joined about 5,000 others who have posted messages in Amazon's online forums calling for the online retailing giant to stop using the parcel delivery company. Some of these have also taken to Twitter to vent their anger, while yet more have posted tales of woe on Facebook."^
I suspect those 5,000 are just the tip of the iceberg.
Have definitely had more problems with Yodel than successful deliveries. In fact, if a parcel hasn't arrived, or we've received a "Sorry you were out" card without anyone knocking then I can pretty much guarantee it was a Yodel delivery.
