They 'attempted delivery', and 'couldn't find the address' So Amazon say contact "your" courier. (The items are sitting at Warrington and have been for 2 days now with no re-attempt at delivery). So forced to contact them, you can't do this on line, you have to do it on the phone, eventually you get to the point of 'enter your 8 digit number from the card we left!' Which having not found the address you don't have! Help line does not let you get any further without this and hangs up on you. There is no other way of contacting them,,, What a shambles, only option is to wait until they can be bothered to return the items to Amazon and then I can re-order in the vain hope that Amazon use an alternative courier, what a garbage company Yodel are, and Amazon are equally at fault for using these guys.
Footnote: Having contacted Laura via the Yodel social networking email address, she did expedite this for me and sorted it out very quickly, thank you Laura for your help, you are a credit to what would otherwise appear to be a very haphazard company.
