Not sure how you would go about that

or how a seller in China (as yours was) would even know. Or how any overseas sellers would know every piece of information for every product for every individual country they sell to

Or why it is any seller’s responsibility to do so more than it is for any buyer to do their homework or ask a question before buying

Just as if someone walked into a phone shop overseas to buy something and did not ask ‘will this work in Australia’ because the shop assistant should tell them it won’t 

Something of this nature is, in my opinion far too important to buy from an overseas seller anyway, even if it did work up front, there is no telling how safe it is or how long it would work before other problems camr up
