Perfume Spray lid not working

I bought Perfume for my sister's birthday last year. 100ml Clinique Happy. They confirmed that this was the real one and not the replica. However she only opened it this year to start using. The spray lid is not working and I cannot get the perfume out. I paid R879 for this (which looks to my now it is a reject). They refuse to exchange, fix or refund this item because it was bought last year. Now what am I suppose to do with a R879 bottle of perfume that I cannot use as it does not spray the perfume out????????? I cannot afford to buy another, neither afford to lose this money. I think that is terrible from their side NOT TO ASSIST!!!! They refuse to give me the manager's details so i can speak to them directly.
