Client satisfaction means NOTHING to Booking.com

Recently, I've made a reservation through Booking.com. There was a certain price throughout the reservation procedure, which almost tripled in fine print when I entered my credit card details, and I didn't see it. I wanted to cancel free of charge - minutes after placing the order! - but that's it, all in vain. They said it only depended on the host, which turned out to be a greedy liar playing tricks on me (when I finally decided not to cancel and check in, he changed the check-in date and matter-of-factly told me I would not be supposed to check in the day after tomorrow, not tomorrow. When I complained to Booking.com, they made him change it back, but then I asked them again to cancel and they still declined, even having understood what kind of a host they were dealing with. I felt like I fell a victim to some gang conspiring against me. Conclusion: client satisfaction means NOTHING to Booking.com!
