New Zealand Panic


I have sent all my teaching samples out to New Zealand with Royal Mail 5 day guaranteed and signed for. I’ve tracked it and it is saying it has been delivered but the ladies on the other side of the world say it has not been delivered yet. I’m going to have a nervous breakdown if they have gone missing as there’s no way I can redo them all in a week.
I thought the flying was going to be the thing that got me stressed but I was wrong.
