Got fully refunded by aliexpress as well. Given my spotless reputation (on their platform), they didn't bother to wait and inspect the returned item that was a bit chewed up by pliers. So, the final cost of the job was an over-priced petrol can that had no use whatsoever. The job also reaffirmed my understanding of the japanese business practices. I am now better prepared if I have to deal with their carp next time.
