Dishonest and ********* business practices

I am deeply disappointed with Southern Sun. They have left a very bitter taste in my mouth. I have been part of Southern Sun rewards program for many many years and after spending a weekend with my family at Sandton Sun and spending R15000 in the process they treat me like trash and refuse to award me even one SunRand. This because I could not secure a reservation through their website and ended up managing to secure a reservation through Booking.com. I paid R1200 more on Booking.com than I would have paid had I managed to secure a booking on the southern sun website. I queried this and manager called Disebo told me over the phone that they cannot inform clients that booking on Booking.com would you forfeit the rewards as this would chase away business. instead she says the reservation counter clerk should have told me. the only thing the reservation clerk told me was that had I booked directly I would have paid less, but she could not do anything now because my booking is with booking.com. yet Disebo said I should have asked her to change the reservation. not only does southern sun treat me like trash, they are also dishonest and *********. see me now see me no more. I will in future stick with hotel groups that value my business
