I have only had one [ touch wood ] that did not arrive, this was recent the seller refunded me straight away, if I have to return one then I do it signed for. I think the service is good. I got one a few years back that arrived with a piece missing a small cheese wedge shape I informed the seller who said it must have been damaged in the post and that I should claim from RM but where was the missing piece I asked, it must have dropped out when unpacking or in transit he said. I don't think so.
