Product authentication help

HI,
one of our perfume product received authentication review as customer claims is not authentic, most likely a fellow seller, searched customer name and is an owner of a perfume shop.

we purchased these perfume directly from the original manufacture brands shop when i was in Doha, Qatar, as the perfume brand and store is Arabic company, the invoice is mostly in English and Arabic.

when submitting these invoices to amazon, it is rejected as they want the whole thing in English which is not possible as the products were bought in august and now i am back in the uk.

any advice would be greatly appreciated.
