Kulula Travel Bank

I've booked flights for May 2020 then lock down came. When I wanted to use the tickets in December 2020, Kulula said I can only use the tickets after February 2021, alternatively, place the funds in a Kulula travel bank account. I received a TB# and upon following up since January 2021, I am now been told that the one ticket was refunded, however, the call center can't say to whom the funds was paid or the account to which it was paid into. The second ticket is still active with Kulula.

With all my follow ups, I do not receive concrete answers, I'm been given email addresses to where I must send the query without success.
