Counterfeit perfumes sold,now they don't want to refund me

I bought perfumes from them,upon delivery we found out the perfumes are not original,I sent jjhuthem an email and they said they would arrange collection of the perfumes and refund me,I have been following up the whole week and they are ignoring all my emails,imagine after they wrote on theor website that the perfumes are original,,such places must be closed for selling counterfeit items.
