Bad service and attitude

I am so dissapointed by the way we were treated like at Cubana Green Point. I booked a table on Wednesday for Saturday the 3rd of March, firstly I was not told that the booking is until 23h00, when we got there, the lady who deals with bookings told us that we will have to leave at 23h00, fine we were there already and we decided to stay. While we were eating we wanted to order and our waitress(AB) told us he was instructed that he must not serve us because our time was up. The lady who happens to be 'Sesethu" came to our table and told us that we have to leave there are people who are waiting for the table, we said yes we will leave, however we waiting for our friend so that we can pay,AB asked where is the friend and I said she went to ladies. Few minutes later Sesethu tapped me on my shoulder saying "your friend is here, you guys need to leave" and the tap was so hash I then told her that she does not have the right to tap me and yet she saw nothing wrong on that, she continued saying " OK THEN BUT YOU HAVE TO LEAVE" and I said to her you are wrong and you don't even apologize yet you raising your voice and she said "sorry then, can you now leave and that is why we don't want to book table for you black people and I will call the bouncer", with my shock I said excuse me?? and she left the table. I went to the front, she was standing with the other lady, I said "can I please have your name" and she said I don't have a name and I asked twice and she didn't give it to me, then I asked the colleague/lady that was standing next to her and she gave me the name.The couple came to the the table, as they wanted to seat, we gave them two chairs but the guy said it's fine we can take the other chair and they did not have a problem with us seating together. AB came to our table and we asked for Sbu (manager), he came back advising that he is busy and we waited, few min later Ivan (other manager) came to us, asking what is happening I told him everything, he looked so concerned and advised that he will deal with the matter and come back to us, up until today am still waiting as he never came back. We are still dissapointed by the treatment received from the staff in Cubana Green Point.
