Dunno mate, you'd think this catches more than a few people out. For overseas purchases you'd prob have to look at what consumer protection provisions that country has (if any) and how it applies to you as a non-resident. Depending on the country it's possible/fair chance they don't apply to you, or if they do, it might end up being be a PITA for you to enforce them from a distance. It does look like the UK introduced new legislation (Consumer Rights Act 2015) that covers internet sales, so might be worth checking out its application to non-residents. That also means there is almost certainly an ombudsmen or regulator that you can bring to the attention of or get some sage advice from. In any case you can be pretty sure another country won't recognise or hold themselves up to another country's legislation (such as the awesome aus consumer law), but withholding parts you've paid for is borderline criminal.
