Good news is that I put in my claim yesterday evening, a day after my 30 day wait was over, and it was approved first thing this morning. I should get the money within 14 days. Thanks Mike G, The tip about sending in the photo of the box with the numbers on was most helpful. I sent in the scan of the delivery note, the electronic receipt pdf and a photo of the box for the serial numbers as as I say, very next morning it was approved.
