I have good news! Rucksack arrived today. I think I know why everything took longer too - from a distance it looks like theres no address on the package. Its probably going to help to write address details to a piece of paper and cellotape that to the bag.
Hi, sorry no rucksack. Keep hold of that receipt so you can put a claim in with the RM if it doesn't show. I am happy to wait until the end of the week and if nothing shows will let you know.
