Complaint Against a Service United Kingdom

Emporio Armani / Giorgio Armani — giorgio armani si eau de parfum intense 110 ml serial nr [protected]

Good Day

I have tried in several ways to contact Giorgio Armani (ref:_00Db0ZVBZ._5000N22fMI1:ref of Armani Online Store Customer Care who referred me to contact me to Armani Beauty Customer Care ) but with no feedback.
I bought a bottle of Si Eu de Parfum on Hamad International Airport, Doha, a while back and having used very little of the bottle, the nozzle is not functioning. This is a first for me and I am very upset, as I do not have the pleasure of using my perfume.
I am a South African currently working in Moscow. I am not familiar with the Russian language or the surroundings and understand that the postal service is not reliable as I could have posted the bottle to you.
I would appreciate your assistance in returning the bottle for a refund.
Awaiting your response.
