Unfair and terrible service by Travelstart and Airlink.

My wife, Elena Pretorius was booked on a flight from Sishen to Johannesburg for 10/03/2021, which was paid for at booking time. On Sunday 07/03/2021 she received an e-mail from Travelstart stating that her flight had been cancelled, no explanation. The mail also stated that if there were any extra costs involved with a new booking the Invoice would be forwarded for payment. She phoned on Monday to find out the reason and after waiting a considerable time was told that there were not enough bookings for that flight. Eventually she was booked on a flight on Tuesday 09/03/2021. She then had to reschedule her connecting flight from OR Tambo to George with Kulula which she incurred extra costs for changing her booking. She had to purchase a new ticket which cost her R629.48. I feel that as soon as a booking is paid for it constitutes a contract between Airlink and the customer(as seen with Kulula), in other words Airlink broke that contract. Yesterday I tried to get hold of Travelstart and eventually got a W/app number. I stated my problem and got an automated answer "Thank you for chatting to us! Have a nice day" I have still not received any feedback from them. I feel that the way Travelstart handled the whole affair was not at all professional and expected more from them. I feel that Airlink must re-imburse her for the extra costs involved. Anthony Pretorius.
