sent so soft and not long lasting

I was so excited for Dior perfume but when I received it and used it for a week I am so disappointed. the scent is gone just after half hour and the perfume is not masculine/intense at all . the smell is so soft and light that after half hour u can't smell it and u have to sniff harder on ur clothes to smell it . I used so many perfumes but I didn't have to sniff the perfume on my clothes to make sure that is it still there .I don't recommend it. I saw so many good reviews about it but now I doubted is it original or not? I want to return it.
