Kulula does not honour the services that they charge extra for

When I booked my ticket for this weekend’s flight to Cape Town from Johannesburg, I paid the extra R260 (R130 per flight) for a FRONT row seat (not an emergency exit seat in the centre of the plane) as I am a very tall person. When I checked in last night, I was given a seat towards the centre of the plane (14D instead of 2D which I booked). I called your call centre this morning to ask why I was not allocated the seat I paid for. The lady at the call centre that assisted me was very friendly, but I’m not happy with the reason that was given for the change. I was told that the first 3 rows of the flight are blocked off for security reasons. I was reallocated to 14D as it is considered a premium seat by Kulula. I do not consider it premium when there is a seat in front of me and I get moved from the front of the plane (which I paid extra for) to the centre of the plane. Who then gets allocated seats in the first 3 rows - the late comers that don’t check in online and don’t pay extra for their seats? And to make matters worse, I received an SMS from Kulula to inform me that the flight at 19:25 tonight is going to be delayed. Huh? How can you already determine that at 5am in the morning? I have cancelled the ticket and have booked a flight on SAA at a cost of R5672.72. Although I was informed that I will only receive a 50% refund, I expect Kulula to give me a full refund (including the extra paid for the seats) as Kulula has not kept to its Terms and Conditions.
