Awful service and kulula owe me a refund or vouchers

hi I hope you can help. We would like to bank our tickets for other family members to use.

We were out from the UK and as when I called in and spoke to the agent I was advised to put my tickets on hold. We were set to travel on the Thursday flight 17 March 2021 at 19:15 from CPT to JNB. I tested positive on Tuesday 15th March and my husband on the 17th March (the day we were supposed to fly). I don't have a doctor here and I did not need a doctor to do a PCR test to tell me I was positive. As we are from the UK we brought lateral flow tests with us just in case we felt unwell. See attached tests. We then had to isolate for 7 days, as by law in SA.

After spending a good 2.5 hours over about 4 calls where I was terribly ill, each with a wait time of 35 minutes (2 where I was cut off) and over R200 in airtime I just got fed up. Also your flights online were exorbitant, so went with another carrier. Therefore I would like to have vouchers for the flights for me and my husband in lieu of these flights. You will see on your systems they have been put on hold. You will also see multiple calls to your call centre from my husband’s phone and daugther's number where she spent a further R200) and you will also see that your call centre.

I emailed about this a good 2 weeks back and am still waiting for a response. Truly disappointed - nothing proudly South African about this service.
