MANGO AILINES IN LIQUIDATION - WHAT HAPPEN TO MY TICKETS?

I BOOK FLIGHT FROM BLOEMFONTEIN TO CAPE TOWN THE 24 AUGUST 2020 FOR MY MOM FOR 10 DEC 2020. 2 WEEKS LATER THEY GO IN LIQUIDATION WITHOUT INFORMING ME REGARDING MY BOOKING WITH THEM. I SEND EMAIL 26 OCT AND THE 1 DEC WITH MANY PHONE CALLS TO THERE OFFICES WITH NO ANSWER ON CALLS OR EMAIL. THEY STILL NOT FLYING BETWEEN BLOEMFONTEIN AND CAPE TOWN. I HAD TO BOOK NEW FLIGHT WITH AIRLINK. MY TICKET VALUE IS R2121.46 AND I WANT MY REFUND PLEASE.
