Refusal to gain entrance at Sun Morula

I am an MVG member of Sun International. Yesterday evening I and my Kids planned to have an evening out at Sun Morula, to my surprise, there were Metro Police at the gate who refused MVG members entrance because there is a jazz event at Sun Morula. I phoned Reception and spoke to lady named Thando, she said they told Metro Police to allow MVG members entrance and I told her I am experiencing problems at the gate, she said she will come to sort the matter and that I gain entrance. I waited for 10 Minutes without her appearing, METRO giving me a hussle, my kids depressed by the situation. I phoned again, she said she will come, and I phoned for the third time, then she said she will send the Manager Mr Tselapedi. I waited for the Manager, he did not come, next thing a Security guy came and ask me Mr Tselapedi has send him to check what type of an MVG card do I have, if it is PLATINUM, I told him I am GOLD, then he turned away, with no feedback, I stood there like a fool and METRO was so making fun of me that they told me I cannot enter the premises. Can you sun International imagine children (4 & 8 yrs) crying in the car when I reversed my car to go back home? I & my kids are so SAD
