Went to pick up a parcel at Click and Collect - forgot to bring order number - a young girl informed "Nohhhhh Nohhhhhhhh the computer says Nohhhhh" you need your number. I'll not tell you what I called her.
Went back with the order number and another sales person - I asked her could she have got the parcel with my name "Of Course - no problem".
Would you have been as annoyed Jenny if you'd turned up to collect complete with the order number only to be told it was collected earlier? Because thats the sort of thing that can happen if you don't stick to the rules
I have used this facility a lot recently, when buying stuff on ebay. I have items delivered to my local ARGOS store, which is every close and convenient for me. I get this email and all I have to do is to show the email on my iphone, to the ARGOS staff...they scan the phone and hand over the item.
