Unfair Booking Process

I booked a flight which was a more expensive flight on kulula.com for the reason that I wanted to reach 6 goals and benefit from my flight booster benefit, so that I can save on my ticket. Only after my flight details appeared on my Vitality Active Rewards, did I see the term appear that no BA flights will form part of the flight booster. Thats when I realised that my flight was a BA flight on the kulula site.

I know its stipulated in the terms and conditions, which I saw afterwards, but this should have been warned earlier during the booking process. Although its part of the T&C's, it is still making me as a customer very upset, seeing as I could have saved R250 on a cheaper flight.

I am very upset with this scenario and expect a better booking process to prevent this from happening.
