I don't like what I'm reading ahah
But, only now I have noticed that in fact, the status is:
Updated on: Thursday 12 November
Item Leaving the UK
Thursday 12 November
Item Received by Royal Mail
So according to the status above, the parcel was with customs only for 1 hour and then the status changed to "Item leaving the UK", maybe will land soon or is just (even if it is odd) waiting for the next plane, who knows...
