Refund still not done

I booked flights and accomodation for a trip to Johannesburg on 11 February 2022 from Durban to Johannesburg. Needless to say my daughter wasnt feeling well to travel and I had included Cover X insurance to make sure I could change my flight details if and when need be. The number for any changes says one has to be physically present at the Airport to make changes, however I could only Uber after making sure my daughter was well enough. The Flight could not be changed or new tickets purchased as it was the weekend. After sending the details of the booking to the Online Company Flight Network for Flysafair tickets, I am still awaiting their reply on my voucher for change of flights to use on different dates. Flights will and always can be changed based on the details or reason that the flight could not be boarded on the day. The Insurance on the flight clearly says they reimburse in 3 days with booking details...I can count its been 6 days with the same automated email..It is in claims..Really??? With all the times I have flown from JHB, never have I ever had difficulty with boarding, or changing details. Durban King Shaka has a long way to go to reach standards that can make anyone change their minds, as in early October, I also had to wait 7 hours for change of flight details with Mango airlines, even after paying R 2700.00 on changes for the day. It is unacceptable to question passengers especially since it is prevalent that we still have Covid to deal with and the nonchalant I dont care attitude from the ground staff at the Airport. They dont lift so much as a finger to assist any passengers and even if they could of course....the question is at what price???? Still awaiting my refund/ voucher for my flight from the Booking Company...feel free to comment if you have a valid answer
