Disappointed at clicks

I’m so disappointed at clicks, yesterday at 17:29 I bought baby milk at clicks. I was suppose to take alula gold number 2 instead I picked number 1 as I was rushing I didn’t realize. When I got home I notice I took wrong milk but it was too late to go back to the store. Today morning I sent someone to return it for me but they refused and said they can’t accept it because it’s another day. The sad part is that the milk is still closed, I didn’t even open the lid. So clicks means that I will have to throw away sealed milk which I bought for 418 because they can’t take I back. I’m really disappointed and I think from today I’ll never set my foot at any clicks store ever again
