AMEX cards not allowed at this Hotel.

I reside in Johannesburg and needed to attend a funeral service in Queenstown, my plan was to drive down on Monday 02/03/2026 and stay the evening as the funeral was the following morning of the 03/03/2026 at 11h00. As I knew the funeral was going to end rather late, I booked for that evening as well. In total of the two nights. I made contact with the Queens Hotel & Casino on the 23rd of Feb. and made a reservation for the two nights. From the start of the telephone call when reserving a room, I explicitly asked whether they accept AMEX (American Express credit cards) as a method of payment. I always try and use this card for flights and accommodation. I was assured that they accept AMEX cards as payment. So, I eventually arrive on the Monday 2nd of Feb. and low and behold, on my third attempt, the lady at the reception counter says "Ooh, sorry but we don't accept AMEX cards. That's when I lost my cool, firstly trying my card on the second attempt, the card machine stated, "last attempt". I know my PIN number and knew something was wrong and that's when the receptionist said they don't accept. Why was I told they do accept AMEX, just to confirm the booking and obviously I'm there now and had to make payment with another card. I know it sounds ridiculous as I had to pay anyway but why was I told YES, they accept?
