well, face on floor he called back!
wont bore you with the conversation details but long and short of it he will take them back for a refund. I have to pay the postage out to me and the return postage even though i know i'm only liable for the return as the mistake at point of sale wasnt mine
wasnt going to argue it as i think the deal is on a knife edge as it is, items being collected from me tomorrow with delivery to them expected for monday at the latest, he's then promising to phone me to confirm the arrival and arrange the refund.
one big fat lesson learnt here about phone orders thats for sure
