Don't book Booking.com

I have used booking.com before and not had a problem but when something goes wrong you are on your own. We ended up in LA with no accommodation just before New Year and no option for anything close to what we had. They offered us an apartment that you wouldn't put a dog in after about 10 hours of calling them. In the end I booked some accommodation myself (after being up for 30+ hours at that time). I have called them about 15 times and keep emailing but still no refund or help at all
