Drop ship company based in NSW. No responsibility for faulty goods. Language problems

I bought 12 small seaparate items as a test. All were delivered but the street address began to change causing major problems with Auspost. Fortunately a good neigbour has been dropping them 4 doors down to us. I live in Gxxxd W... Gardens. My name changed to Mr Gardens. Then to Mr. Then to xxxx. Looks like non-nationals with limited English language ability. None were Australian stock. Now bought a $80 car cam which was DOA. A series of 4 delaying emails and finally an offer to send it back at my cost, it will be examined and if OK returned at my cost ( yeah ! Substitute so I pay) if faulty they will send back to china and await a return in up to 4 months. The classic flying pig proposal. This is a breach of the Australian Fair Trading Regs, as it is the local company only who have contracted a sale with me. Their supplier is their problem.
Been buying on line for years. This one scrapes the barrel. Don't buy from them.
WHEN THINGS GO WRONG, IT'S THE PUTTING RIGHT THAT COUNTS. Yes ?
