Very dissatisfied

I had the worst response from kulula.com after they have communicated with us to be at the airport 2 hours before departure due to a strike of staff,I checked in at about 11:45 am. The flight lands 13:40 which was suppose to be boarded at 13:30 according to communications.than we are told the flight has been delayed until 6:00 pm,at about 4:00pm they supply us with hot juice and water and not forgetting the funeral sandwiches as a small compensation for the delay.i then arrive at king Shaka airport 7:30 got an Uber because the transport I arranged could no longer wait for me because of work commitments,so I get to my place of accommodation around 8:00 which I should have booked in at 2:00pm so I lost the benefit of enjoying a day of my honeymoon because of kulula,when I mail them I get a guy who responds two days later telling me he can refund me with a R300 voucher for my next flight so what happens to my accommodation fee which I have lost due to their poor planning
