I had a Recorded Delivery dropped through the letter box the other week unsigned!! but I caught my postman on the way back up our road and gave it him to scan and let me sign for which he was very grateful but it just goes to show it can happen. He says it was not a big problem but if it had been Special Delivery he told me that he could have been in trouble, but they are only human and accidents do happen. I know this may not help you, but I think it answers your question good luck with finding the record. Atb John
