Booking.com steeling my money with!!!

Well, what can i say??? Made a booking through booking.com for an overseas business trip, specifically chose a free cancellation option with "pay at property" option because my dates aren't set in stone yet. I even took a picture of the option just before i confirmed the booking. To my shock the booking confirmation came through as a no cancellation booking and the total amount was taken from my company credit card! Now booking.com and the property doesn't want to correct this and i'm just losing the money!!! I've been going back and forth, sending them the picture i took, explaining everything but they just say "you chose the wrong option". They are not even trying to rectify this or help me out! Absolutely absurd and disgraced about this!!! Now my emnployer wants me to pay back the money...leaving me with no salary this month!!! Thanks booking.com!!!
