Refund for the ticket bought during lockdown refused by Kulula

I bought the ticket during lockdown, it is not my fault that the ticket was cancelled and now Kulula is refusing to refund me my money. I told them that I will not be travelling using airlines for sometime since my reason for travelling was work and now I'll be working near home. The lady who assisted me said I will have to find a person to buy my ticket, how? who still trusts a random person these days, Kulula please review your decisions coz to us it is more like you are ******** people and this is not good for your business. I did send the e-mail in April asking them for a refund but I could not be assisted, all I was getting were automatic replies... I should actually be claiming back my money with interest.
