Won't recommend Bossa Milnerton at all

So this review is not for Bossa Burgundy but for Bossa Milnerton, could not find it on hellopeter. Me and my work colleagues booked a table at Bossa Milnerton 3 weeks in advance, we booked for the 5th of December. The Day started off well until we were told by our waiter they want us to move as there is a bigger booking coming in, yes we were a small group but we were 6 people, we booked a table for a reason so that we wouldn't have a problem finding a table as its Summer and it'll most likely get busy. We complained about this, left it then went over to their bar area. We couldn't find a table but then decided to sit at the bar on the side, as the night progresses we obviously enjoying ourselves and a few of our party leaves. We then had my colleagues boyfriend join us and 2 other females join us. They serve him and the 2 girls their drinks, we then proceed to order and are told by the bartender he will no longer be serving us. He states that our one colleague has had too much to drink, we call over the manager who says the same thing and now they will no longer be serving the rest of us as we will be giving him alcohol if they serve us. Firstly none of us are driving home, I get that you don't want to serve him but refusing to serve the rest of the people of colour but will willingly serve the 1 white person in our party, in South Africa today, we were so disgusted and left. But it honestly left me hurt and the rest of my colleagues, not ever has this ever happened to me. They had no valid reason to stop serving us, we weren't rowdy or even causing a commotion we just wanted a night out after what this year has given us.
