iPhone 7 Repair Program for "No Service" Issues problem

I'm in Australia. I have a broken iPhone 7 which has been assessed by an iPhone authorised repairer in Australia as qualifying under the: iPhone 7 Repair Program for "No Service" Issues. My iPhone 7 model # A1779 has been identified as made for the Japanese market, as such, Apple Australia refuse to assist me.

I sent the iPhone with detailed instructions in English and Japanese to Apple's 'Warranty Obligor' address in Japan. Apple Japan Inc. sent my unopened package back to me advising that I should've sent my iPhone to their repair centre (they didn't give me the address). I sent an email to Apple CEO regarding this - no answer!

Where do I go from here to get some customer service?
