Hi Warren,
Thanks for that link. Cettainly offers some hope. I followed through to the ACCC site
http://www.accc.gov.au/content/index.phtml/itemId/3863 which, on reading, suggests that since I purchased prior to 1 Jan 2011, I should look at earlier laws. I thinks its getting to the "too hard basket" stage for what is essentially a minimal loss.
