Particularly via a locker?
My order has been at one time or another...
On its way.
Delivered to locker
Unable to be delivered so on way back to seller.
Waiting in locker.
Collected by me.
And on it's way from the seller.
In that order.
Oh and when I went to see if the item was there it was the wrong item but there is no option for 'wrong item sent' in the I Have a Problem report thing.
