Spray nozzle splashing - how to fix it?

Hi, I have a problem with one of my perfume bottles. It`s the beautiful La Petite Robe Noir by Guerlain.
It gives just a little splash when you apply it. Does anyone have a good advice of what i can do?

Could you return it to the store?

I bought it as a tester, so no. It didn`t have this problem at first, but came after some days...

I haven't tried this www.leaf.tv/articles/how-to-fix-perfume-nozzle s/

I hope someone that has had a problem can help you.
