If it's a spritzer bottle, then it's not a "refill."
Those bottles commonly have the pump-spray mechanism fused to the bottle's neck. They are often not separable.
The pump-spray mechanisms are also notorious for failing before the bottle is empty.
Other than manually pumping all the perfume out and into the other bottle, your options are rather limited.
Have you considered sabring?
I hear the French are pretty good at it.
If you can make a couple vertical cuts to the metal collar on the neck, you could pry open the collar and remove it... delicate work.
Or, perhaps best to return to the women's perfume bar and pursue further enquiries...
