I ordered two items yesterday, both totalling to about £230.
I arranged same day delivery. Items were due that evening between 7pm and 10pm.
By 10pm, they still hadn't arrived so I put in my order number on the tracking part of the Argos website.
Order status = Delivered.
When I look some more, it says the delivery address - Not our address but same street, just a different number.
They delivered to No. 15 instead of No. 50!
I went round this morning and No. 15 on our street have no idea, they haven't got it, they say.
I ring customer services just now and got put through to the fast track team. He's taken my number and will be looking into it for me, but he said "not sure what I can actually do though as these are very expensive items" 
This is my second home delivery disaster within the year! The last was my bloody wedding dress - Which I eventually got hold of after a lot of hassle. But we were in a different house so I can't ping it on lying neighbours anymore.
AIBU to want Argos to be less blasé? DS is due soon and that order contained his car seat.
