I paid for a letter to be tracked and signed after it twice failed to be delivered by NZ post. This one was supposedly left on a chair at the address although it had a post box and was supposed to be signed for. Suffice to say it has never been seen. Very suspicious to me. Contacted NZ post who seemed to think this was alright and I should claim from Royal mail who sent it to NZ even though NZ signed for it. Avoid at all costs. I wish I had seen all the revues before using them.
