Terrible - New version just as bad

Just stopped working. Everything looks ok but booking fails with an obscure "invalid argument" error message. No way to contact them to fix app. Take a cab! Impossible to book, getting now an error message about payment method having expired even though expiry date is years away. Just lousy. Went from essential to zero overnight! TAKE A CAB!!!!!!!
