UNCLEAR baggage allowance rules cost unnecessary money

I am very disappointed with Kulula’s transparency and communication regarding baggage allowance! When booking my ticket the system asked me to choose between fly light option , pack and go or fully loaded. The fly light option has a picture of one person traveling and the pack and go a picture of a family with children. Since there is NO explanation of the options when you book I took the option with only one person in it (since I am not traveling with kids). NO WHERE on the EMAIL kulula sent or on the BOOKING CONFIRMATION did it state the baggage allowance. I therefore assumed it would be standard 20kg check in and 7 kg hand luggage. When checking in I had to pay an additional R410 for my 1 standard 20kg bag of luggage. This is so misleading! Kulula, please update your booking process so that it is clear what you are booking!

Also please give me a refund for the additional fee paid for baggage since it was not clear at all on what is allowed on the flight.
