Rude and drunk manager

I checked the website on the 24 the of December 2023 in order to have Christmas lunch with my family. The price on the website stated that Friday, Saturday, Sunday and public holidays is R245. 90.The only available term highlighted in Red was the times may vary, nothing about the price. When I got to the restaurant on the 25th of December around 11h00, ready to enjoy myself with my family after driving all the way from Midrand. I was told by the waiter that the buffet price today is R430. 00 and when I asked to speak to the manager, floor manager Taffie was called and she confirm the price of R430. 00 and I asked her to speak to the manager and she came back saying the manager is available and it stays that the consumer protection is not respected because of false advertising. I then requested to see the manager Cameroon Morris who came smelling alcohol and insisted that that the chalk board is written terms and conditions. I told him that I checked the website yesterday night and got the number for enquiries on the website ***), send the message to verify what I saw on the website and there was no feedback. Cameroon Morris was rude and shouting at me and said I can report him anywhere, he doesn't care. I used my own petrol and time only to have to drive around again looking for where I can have Christmas lunch. Consumer protection Act is not respected and the management.
