Request refund of MN455 passenger tickets x 2

We paid R4376.38 for 2 passengers to on MN455 from Lanseria - Cape Town on 12 March 2022 at 17h10 - 19h10.

The flight was cancelled, I received a call from the airline regarding the 24-hour suspension from the CAS due to engine failure - which is a concern of my life should I have been on a flight where we would've lost engines and crashed.

On the day, we couldn't get another flight out on the airline so we had to pay for alternative tickets on Safair to fly out of OR Tambo to get back to Cape Town on the same day. This put us under more financial pressure that hasn't been relieved. The following business day, I received no communication from Kulula. Needless to say, I sent an inquiry to Kulula to ask for a refund of my money and no one has responded. I repeat, NO ONE has communicated to me ever since and I am not letting this go. I will not accept a voucher, I want a FULL refund of the 2 passenger tickets on those flights + the R130 paid to reserve the seats when I paid for the tickets in the first places. That comes to R4376.38.

The customer service received from the Kulula is abysmal and absolutely unacceptable!
