A travel booking nightmare

The bank is great and the app works well. HOWEVER, the authentication process is super tedious and 6 out of 10 times does not work. I appreciate the thinking behind the tech to make banking secure but it is highly frustrating that there is no alternative - like the widely used PIN sent via SMS. This authentication process turned a travel booking into a nightmare. Four days of searching flights, six phone calls (one 90 minutes long) with the travel call centre finally sorted my problem but suffice to stay the programming of the travel page needs work. What is the point of offering discounts for being a Discovery member and doing all the work to get Vitality points to secure the discount when the travel portal only gives me flight options with NON-partner airlines where the discount is not applicable? The three call centre agents who assisted (the lines were not very clear so I may have the names wrong) - Tobeka, Christine and Sipamandla - were champions despite my growing irritation, frustration and impatience that the travel portal does not work as promised. Please, Discovery, I have been a member of the medical aid and Vitality for decades and a client of the bank since June 2022, sharpen up the travel experience. PS. This was for international flights.
