No refund in over 10 weeks

Good day

We booked return flights to cape town but had to cancel due to COVID 19. We were given the FlySafair voucher immediately after canceling but haven't received a refund for the kulula flight. I'm was told my refund was processed and it takes 3 to 8 weeks. The last time I followed up, the weeks had changed to 12weeks. it's my 10th week now waiting for my refund, I really hope my refund will be in my account on the 12th week. I'm tired of waiting for my money. Kulula informed us that travel agents must pay us they don't have any refunds to process on their side.
