The seller is in NSW. I realise they won’t just take my word for it but when I used the link ‘report this item’ it only allowed me to give a very brief outline of my issue before the automated reply. 
I was hoping to send photos of what should be on a genuine pair and what is one the pair I received. 

I have decided to return the item as the markings in the photos don’t match what are on the sunglasses I received so it is not as described. 

I don’t really want to give the item number. I am new to this and not sure what issues this will cause revealing this.
