Left me on the street

I booked a place last night and when I arrived there was no keys or hot water at the property. I canceled the booking and booking. Com agreed to refund me but within 7 to 12 days. I then had to book another property at 11pm. Today I booked another property and drove for over a hour to get there just to be told that the property is not available and I must cancel my booking. I contacted booking. Com and explained them the issue with the property. And again I was told that they will refund me. But I have to wait for 7 to 12 days. The issue is that I used what ever spare money that I had to pay for the bookings and I tried to explain it to booking. Com that I have no more funds to pay for another booking as they have not refunded my 2 previous bookings. I was advised by their customer service agent that I must borrow money from my family to pay for another booking from them while booking. Com has my money which they did not refund me. They can not even book other accommodation for me using the money that I already paid them. I am forced to sleep with my wife and 4 children in our vehicle at a garage. I am so disappointed with booking. Com for putting us in this situation
