Poor customer service at Kulula.com

I bought a return ticket from JHB to DBN just before lockdown in 2021. Bought it on 5 April 2021 for use on 9 April and back on 11 April 2021. All regions were then put on lockdown. I called Kulula and a voicemail referred me to their web site for assistance.The website stated that the tickets would be valid for 12 months. Since the beginning of 2022 I have been trying to contact Kulula to find out how I can use my ticket and not lose it. Their website is a total waste of time and you hold on forever and still dont get to speak to a person. The ticket cost me R2105.18 and I would like to get another ticket or my money back.
