Poor service

I booked accommodation through booking.com and my account my debited the full accommodation amount. There was no indication of money that i had to pay as yet. There was an option which I clicked to pay at the property the next thing I see my money is out of my account. I cancelled the booking immediately. I got confirmation straight away that my booking has been successfully cancelled and that the refund should be paid back shortly. I am still waiting for my refund. I phoned booking com this morning and the lady told me that the accommodation party must do the refund they do not deal with refunds. So after phoning the accommodation and was told that booking.com must pay me back I am on the point of having a nervous break down. R3326 was debited from my account which is alot of money and now I am in the middle of this fighting for my money. I do not care into who's account went into I want it back and immediately.
