Flight booked during national lockdown

My husband and I both booked flights with Kulula which was meant to take place in March 2020. Needless to say, because of the National lockdown, we could not make use of the flights.

Now when we are trying to utilise the flights, we are being charged a booking change fee and apparently because our previous flights were with BA, we are now being charged even more.

I do not understand the concept, we had no choice, we were not allowed to fly, but WE have to bare the costs of changing the booking. How does that make sense?

In addition, and keeping with the experts' advice and requests of our President, we elected to not travel, so we have not had the chance to utilise the credits (in our minds we were being responsible citizens during an International pandemic). Now we aren't allowed to anymore...?

You never fail to disappoint Kulula. Good luck trying to keep your business affloat.
