Take a lot is a ****mer and they sell ****s

Take a lot sold and a **** perfume and they are refusing to refund me back my money. I bought a perfume from them and the lid of these types of perfume is magnetic but on the one I received from them the lid was not magnetic and also when I used it for the first time the perfume was very light and it is like it was mixed with water and it doesn’t last at all. I’ve had this perfume before and I know how it smells and how long it lasts. Now they are refusing to refund me back my money because the perfume has been used. I received my order on the 27th of October and I logged the return on the 30th of October and the perfume was used only once when I tried it - I am confused on how they would have expected me to know that the perfume is mixed with water without me spraying and also when I called them I did state the reasons for my return
