R159 pp Buffett with NO PRAWN

To whom it may concern

I don't understand how you wait until I have ordered to inform me that there is no prawn as this is a big attraction when it comes to sushi.

Furthermore, I don't understand how you can still charge R159 pp for the buffet which means "ALL YOU CAN EAT" if I cannot eat it all because you have no stock??

This is a *******!! There are ready so much plates that we are not allowed to eat because it does not fall part of the buffet yet I still have to pay full price even though there is no prawn?

I want answers!!!
