Bad Customer service

Today I went into the Woolworths Canal walk store, I was there to exhange a gift I had gotten. A lady from the customer service tills assisted me and had to confirm with a manager because apparently the gift was a high priced item, which was fine I waited while the lady went to speak to her manager who wasn't far from where I was standing. The strange thing is that this manager named Jacques had to take a peak at me before he could make his decision,the lady came back to me and said they needed more details about the item, I told the nice lady that it was impossible for me to give her those details as I was gifted and do not know exactly who gifted me as I had a lot of people that gave me gifts, they said they couldn't help.I requested to speak to this manager who basically repeated the same thing and I asked him what would happen in my case because I don't have these details he said I needed the receipt for it, I then had to repeat myself again and reminderd him of the Woolworths' return policy but this guy refused to exhange this item and said it was a manager's discretion. I asked to speak to someone higher and waited for about 30 minutes with no updates from anyone to tell me what was going on. Eventually this Jacques guy comes back to tell me that he couldn't find anyone to assist me. He made a few calls infront of me and told me someone was coming to assist me and so I waited for a longer time. After 20 minutes a guy named Kevin who is also a manager came by but was not there to assist me but to assist someone else which was fine, another lady(employee) called this Kevin guy and told him my story, I was sitting right there when they spoke over my head. This guy said, not addressing me "What does she want, didn't she speak to a manager already and why is she wasting our time' he turned and looked at me and rudly asked me "what do you want, didn't you speak to a manager already? What do you think is going to happen because nothing will change, why do you need to speak to another manager?" I calmly rep**** and said "excuse me, are you here to help me? He said "No, someone else is coming but nothing will change" I didn't ask him what he was talking about because initially he did not address me. I told him I had the right to request for further assistance if I am not pleased with the manager that I had already dealt with. then left me hanging like that. I have never ever been belittled the I way this guy did, he practically took a look at my face and treated me like trash in front of his staff! It's shocking and sad that at this day and age, the colour of my skin played a role in deciding whether I deserved respect or not as a customer. I sat there humiliated by a manager. I don't know if that's how all Woolworths customers are treated but I will accept it. I want the Woolworths executives to see this and I also want the Ombudsmen to see this and tell me if it is an acceptable behaviour? Further than that I will not rest until Kevin has been dealt with accordingly! I will go to the media if I have to in order to be heard.
