Refund debacle

On the 4th of February I searched for a night stay on booking.com and I saw one amounting to R468 at Ezulwini Air bnb and I made payment ,whilst waiting for confirmation the owner of the place sends me a message and tells me that the room is actually R1200 and that booking.com had made a mistake ..I then asked for a refund and she's stated that the refund is with booking.com as she only recieves the funds after 7 days ..I've been going from pillar to post the only communication from booking.com is an automated email with no way forward.
