Mango Air refund policy sucks especially during coronavirus

I had booked a flight for my elderly parents from Johannesburg to Durban for 19th March 2020 with Mango Air.

They were supposed to fly arrive in Johannesburg from Nairobi with Kenya Airways but due to the sudden restrictions placed on the day due to the outbreak for Coronavirus, they were not allowed to board from Nairobi on the Kenya Airways flight.

We contacted Mango Air for a refund as this was unforeseen and no our fault. They said they can only provide a voucher to use later and cannot provide a refund. This is really unfair based on the circumstances as they wanted to fly into South Africa and go to Durban before heading onto Dubai with Emirates and then to the UK.

We have received notices from both Kenya Airways and Emirates that they will refund the flights or re-route or reschedule them. It is sad that Mango Air cannot provide a refund as my parents will have to avoid South Africa and fly directly to the UK.
