Kulula.com is running a ****

I purchased three return air tickets from Kulula.Com on the 1st of March 2020 from (flight 1) Joburg O.R.Tambo to Durban King Shaka. Departure date 27th March 2020 07:00 arrival 08:05 Flight 2: from Durban King Shaka to Joburg O.R.Tambo. Departure date 30th March 2020 19:15 arrival 20:20 Kulula booking reference number HDFZTM, airline reservation code TFV265, Carrier British Airways. Total cost R6066.66 invoice number *** Due to the lockdown that President Cyril Ramaphosa announced that restricted us to travel between provinces and the closure of all domestic flights we were unable to fly. I recently contacted Kulula.com. this is after having to hold on for almost 30mins before someone answered by call. requesting if I could use these tickets again for the same three passengers and provided the departure date of the 28th Oct 2021 and departure date of 1st Nov 2021 for the same destinations. The answer was Yes, however I would have to pay an additional fee. I was provided with three options for each the 28th of Oct and three options for the 1st of Nov. Departure 28th Oct 08:45, 11:55 and 17:20 (leaving Joburg) and arrival on the 1st of Nov from Durban 08:45, 13:40 and 19:05. Option 1. Departing Joburg on 28th Oct at 11:55 and returning from Durban on 1st Nov at 13:40 would cost be an additional R5069,31 + original tickets cost R6066.66 = R11 135,97 Option 2. Departing Joburg on 28th Oct at 17:20 and returning from Durban on 1st Nov at 08:45 would cost be an additional R3518.00 + original tickets cost R6066.66 = R9 584.66 Option 3. Departing Joburg on 27th Oct at 17:20 and returning from Durban on 1st Nov at 08:45 would cost be an additional R2930.31 + original tickets cost R6066.66 = R8 996.97 plus I would have to pay for an additional nights stay. I was also informed that i can only re-use these tickets up until the 30th of November 2021, thereafter they cannot be used. I cannot also get a refund. We could not travel because of the lockdown restrictions which was a stipulated by the government which we had no control off. The additional amounts that I would have to pay on top of what I have already paid for to Kulula.com is too much plus the cost of accommodation in Durban had made it unaffordable therefore we had to cancel all plans. It is absolutely ridiculous to have to pay so much more in addition to what I have already paid, They refuse to also refund the monies back that I have paid. I am an ordinary working class man who wanted to take my wife and daughter for a short vacation and now I cannot also get refunded. This is an absolute ****.
