Covid19 Refund since March 2020

HI...last year we were scheduled to fly to Durban from Johannesburg , bought return tickets. Due to the lockdown our boat cruise (MSC) trip was cancelled and we have been trying to get our refund from Kulula to date still no refund. MSC gave us our refund, we logged a refund with kulula last year March, spoke to a lady by the Name of Unathi Ngalathi on the 27Jan 2021 to further process our refund still no response. 20 minutes on the phone today no-one answered my call at Kulula. unfortunately one of the passenger who booked with us passed on due to Covid19 while waiting for her refund. Please bring back our money....
