****** of my Qualified Reward

i am on a week vacation in Sun City and an MVG card holder. I go to the casino daily. As it is a norm in Sun City Casino, the more you play, you qualify for a drink reward. I qualified yesterday. I called the waiter to provide the service and she said she is coming back. I waited and waited, she could not come. I looked for other waiters, there was no one on the floor.I then went to sun Downer to ask for serice, the guy I found there told me he will send the waiter to me and asked which machine am I playing?. I told him I am playing at SunStrikers, I waited and waited and no one came again. The lady who told me she was gonna come was sitting at Sun Downer when I went to ask for assistance doing nothing. I am so disappointed in the service of the staff that was working last night at the Main Casino Floor. Do they know how much a player have to spend to qualify for a reward? if they knew I believe they would have respected my call. Is this what the waiters in sun City casino do to the players? or do they do this to those that they dont know as i have indicated that I am on vacation. I need my drink I qualified for it like the rest who qualified last night and anytime before. I left the Casino at 02h37 this morning feeling disappointed. That staff that was on shift are rude and treat customers bad and unprofessional. I am writing this because I I hate people like those who were on the floor last night; I afford to buy myself a Pack of drinks, but since this is a reward and courtesy for players I believe I deserve it and I need it. I am living the Hotel on Friday. Awaiting to hear from you Sun City Management.
