Well. This one has a happy ending - I just got a £6 partial refund on my white strap taking the cost down to £8.50 with P&P. It came with everything I needed for the wife to wear it anyway, so despite a lengthy ping pong email conversation I'm quite happy with the end result. Truth be told best I was hoping for was £2.50 back as goodwill refunding my postage.
What was wrong with it to make them give you a refund?
