I have to say I'm not overly surprised.
I have a friend currently living near Berlin, and her mail from the UK has been "vanishing" since Xmas. 3 parcels and an important letter so far undelivered, and neither Royal Mail nor Deutsche Post can offer an explanation as to where they are.
But where do these things go? Do they just fall off the back of the lorry? Or get lost under a pile of stuff in a sorting room?
