Booking.com review: Booking.com is a scammer

I will never again use scammer booking.com. My flight ended up costing double what I paid because booking.com didn't warn me that if one leg of a multi-leg flight was cancelled by the operator, booking.com wouldn't reroute the flight. Although I bought the whole flight with it on one ticket, they said it was totally my problem. Last minute booking cost a fortune. I used to like the app for hotels but now don't trust it for anything.
