so there isn't a direct line phone number?

"Amazon Customer Service handles all enquiries for Amazon Logistics."

what else?

"If Amazon Logistics can't deliver your parcel on the first attempt, delivery will automatically be re-attempted up to four further times. The parcel will then be returned to our Fulfilment Centre and a refund will be processed to your payment card."

well you know...somebody is pissing around...they could easily post it through my frontdoor letterbox....and so perhaps the best thing is to let them pretend to try and deliver it 4 times...to then refund the lot, to my debit card...and then have another go - after Christmas?
