Sun Internation does not care to respond to my horrible experience. Its over a month and nothing!

Sun International definitely does not care about their customer experiences. I had an extremely unpleasant stay at the Wild Coast Sun on 13/14 October where I experienced 1. Theft, 2. Brown & contaminated water and 3. Entertainment facilities not working. I requested to speak to a manager on my stay but I was told that they are not available and I should contact the manager after my stay via email/telephone. I sent numerous emails and made several phone calls, only to be told that they will get back to me. It is one month later, and nothing! I cannot believe that as a 4 star establishment, they can do nothing to make a customer feel happy and satisfied with the money spent (or wasted in this case). I am extremely disappointed and wish to cancel the booking I have but no one will respond to me! What a waste.
