Sun protect anti aging face cream

I bought a Sunscreen at Clicks Cape Town Eester river, it has a weird smell it was smelling like it’s old, and when I returned it they said I lt has been used they can’t take it but I bought it Sunday afternoon and returned it Monday, I heard the smell when I was rubbing it on my face and I immediately rinse it off, the bad thing is that the sunscreen is for face and I can’t use it anymore. And they said there’s nothing they can do about that whereas the sunscreen is smelling like a toilet, and I have been using the sunscreen for 2 years now I know the smell of it, They Manager said the sunscreen doesn’t have a good smell i must stop buying something I don’t know. I am so disappointed.
