Extremely dissatisfied with Bidvest International Lounge

My mother flew from Germany to SA (via Paris) and arrived at OR Tambo Int. on Saturday 6 Dec '25. Because of a change in flights made by the airline she used, her next flight was scheduled for the following day 9am (Jhb to Kimberley). I then decided to purchase a ticket for her to wait at the Bidvest International Lounge until the following morning (I bought two tickets seeing as one is valid for 4hours only).

Upon arrival my mother was informed that the lounge is only for International DEPARTURES and she was denied access. I've checked the website again and NOWHERE does it specify that the lounge was for international departures and NOT arrivals. My mom had to wait on a bench for 9hours for her next flight.

I expect the R1216 that I've paid to be refunded. The website is not clear about this and neither was the lady I spoke to when I phoned the international lounge before I purchased the tickets.
