Perfume rip-off

I bought a 212 VIP Rosé Elixir for R3000 which I absolutely love. The issue is that the perfume barely even lasts for 2 hours. I have used 212 VIP since my varsity days and never had such an issue before. I tried calling the customer care line and I am being sent from pillar to post. It is really disheartening to spend so much on a fragrance that I have to constantly apply.... Makes one question the authencity of their fragrances!
