Gucci Guilty Perfume from Sephora Doesn't Last

I purchased the 'Gucci Guilty' perfume from Sephora. The scent lasts only 5 minutes on me. We sent the product for review, and the company responded by saying 'there is no issue with the product.' It's unbelievable... I paid ₺2600 for a high-quality perfume, but it turned out to be worse than refill perfumes, and supposedly the company's expert claims there's no problem. Sephora's quality is on a steep decline; they never stand by their products or customers. I demand a swift resolution to this issue. Please contact me!
