Tsogo Sun - bad experience before you even book in!

On 02 September 2019, my sister and I went on to the Tsogo Sun website to first book Gold Reef tickets. Firstly, when entering the platinum card number we kept getting an error. I then phoned in, after an hour and a half of being pushed from pillar to post with no one being able to help. As the managers that actually had training on the system were all on leave according to the staff member. We decided to book a room so the kids could have two days of the park. I called in to central reservations to ask if I booked two rooms for four adults and two kids would that be fine as the moment I select more than two adults on the side I get a no availability message. If I change it to two adults I then get lots of options. The gentleman assured me that I must go ahead and book as two kids younger than 18 stay and eat for free. So I must just include a note in the booking that we are bringing kids, which I did. I then made the book and paid, two different transactions as again the system didn't allow me to pay for both rooms at once. Issue again! I get an email straight after the first room confirmation booking that the reservation was cancelled. So then I call again to find out what is going on as the money left my account and now I have one booked room and one cancelled room. I spoke to Robin who said that they assumed I doubled booked by mistake! This is ridiculous! People book more than one room! Eventually Robin booked the one room again for us. This was done at 14:20. We started this process at 09:00 in the morning. Then we checked the website again and saw that now there was availability for check in 4 Sept and check out 5 Sept so we wanted to change the reservation to these dates from check in 5 Sept and check out 6 Sept. So I called in and once again transferred from person to person. Then the lady I finally end up speaking to says I should have booked family rooms! I explained everything as above. She says that I phoned their call centre and she will take it up with them for providing wrong information. So I said but that doesn't help me! This is frustrating and I will never book with Tsogo sun again! I spent the whole day on the phone. My phone bill increasing and just no help at all! Worst experience for something that should be simple.
