Issue with Return Flight Booking

Dear Flight Network Customer Service, On 28 November 2025, I booked two flights for my husband and myself from Durban to Johannesburg for 13 December 2025, with a return on 14 December 2025. The booking reference is 1109-846-117. The booking details were as follows: Outbound Flight: Airline: Safair Airways Date: 13 December 2025 Departure: Durban at 20:05 Arrival: Johannesburg at 21:15 Return Flight: Airline: Lift Airways Date: 14 December 2025 Departure: Johannesburg at 08:00 Arrival: Durban at 09:10 The payment for both flights was successfully processed without any delays. The outbound flight on 13 December went smoothly, and check-in was effortless. However, on 14 December, when attempting to check in for the return flight, I discovered that the booking for the return flight was never confirmed. I received no communication or alert indicating any issue with the booking, despite both flights being booked together. I attempted to contact Flight Network immediately but was unable to reach anyone. As a result, I was forced to purchase a completely new flight at a significantly higher cost—approximately R4,000—to return to Durban. I am extremely disappointed with this experience and the lack of support provided. I have sent the company a email I'm awaiting feedback.
