The RM refund page says I have to wait a certain length of time before I can make a claim for a lost item. That time has elapsed now, but....I need to find the postage receipt. I didn't send it signed for, so I may only may able to claim the cost of postage, not the value of the item.
As I said, I'll dig out something else to send you - signed for this time.
If the headband turns up after you receive the second item, just keep it. No problem.
