In addition to the addition, do not go for a replacement — unless the seller is an authorised Australian business for that item.
Just get a full refund.
The reason for that is that if the seller sold you a non-functioning item the first time around, the likelihood of receiving the same sort of non-functioning item is high. Especially if what you purchased was a Chinese unbranded item, the problem in the item is probably intrinsic and the failure of the item to work properly would have happened anyway, probably within a year. That’s much too late for any remedy, and as mentioned the MBG is not a product warranty. You’re possibly lucky that the failure was immediate, so that you’re not dealing with a warranty issue but rather with Item Not As Described. That is covered by the MBG.
Act now. Your options diminish as time goes by.
