Booking.com Take No Responsibilites For Their Mistakes

Used booking.com to book a hotel and since the site froze and received no confirmation or any contact from them what so ever, decided we must of not got the booking only later to be charged for accommodation as a no show. Booking.com told us it wasn't their problem and hung up. After calling several times they claimed to not have our email address so couldn't send us confirmation though after speaking to the hotel we were informed booking.com have them our email address so they could contact us. No email they said even though we have received n umerous emails offering special last minute deals. They do not care about travellers nor do the take responsibility for their mistakes. They are shonky and untrustworthy and I deeply regret ever using them. Will steer clear of them from now on
