'Show and stay' website claim false and misleading

false and misleading claim on website . I attempted to use their 'show and stay 'option which they claim will give a discount of up to 50% of their 'Best available rate'. After having to prove that I had booked a show they then sent a quote for their Sunsquare hotel for one night ,after discount of 50%, R1485. Thinking this was more than expected I then tried booking a room for the same night ,I was quoted for their 'Best available rate' a cost of R1870 . A difference of R550 when 50% discount is app****. Do they think their costumers are stupid or are they blatantly *********** patrons on the off chance they won`t check . also complained to their reservations dept. but no reply.
