Neran refuses to replace a screen glass protector

I bought an iPhone 6 Gold 16GB at The Glen mall that had issues and returned it within 7 days. Last Saturday I decided to get my new phone. I told them that I wanted a Gold one and they didn't have it in stock, so I told myself I'll take whatever phone they have because it has been more than a month since this matter hasn't been resolved. When I got to the store, they told me on the system it shows the phone has been rejected so they can't give me a new phone. I told them that their consultant dealing with HelloPeter queries told me that I can go and get a new phone. After arguing, Neran decided to give me a new phone. He told me he's giving it to me from his own pocket because he's not sure whether I'm telling the truth. I assured him that it is the truth and he'll find out on Monday when the offices are opened. As I was trying to tell him about the Screen glass protector that we bought on the same day for R199, that we'd like a replacement. He refused to give me one and said I must talk to the Repairs Centre which is absurd. Please replace my screen glass protector which I had bought for the phone that I didn't know would be damaged goods.
