I attempted a jbhifi meb

You said you're hitting Myer with the broken glass method.

I was told they were unable to refund due to no "fault" and that they would have known that it was empty before picking it out and sending it to me.

On the grounds the fragrance cannot be viewed externally and the weight Is within the MEB's weight bracket, tell them to provide evidence that clearly demonstrates It was In the box at the time of packing.

If that fails, I have another approach that they cannot fulfil.

Should I attempt to contact jbhifi directly over live chat instead of the actual store?

Go with whatever you're comfortable and most Importantly, confident with.
