Witholding my refund under false pretense that Emirates never paid

Booking.com is a ****ty company and needs to be boycotted. I have called them since 1st week of January trying to get my refund for a cancelled Emirates flight. They claim Emirates has not refunded them, however Emirates has confirmed and sent proof that the refund was processed on the 1st of January which was 3days after my cancelled flight. It is now the 1st week of February they claim Emirates has not refunded. I will fight for what rightfully belongs to me. Release my funds or i will drag you through the mud till i run out of my last breath.
