Hello
I bought the same product twice by mistake because the first time it said the purchase was unsuccessful even though it was successful.. Where can I request a refund for one of the products? Because I contacted any party who says that this matter has nothing to do with us? Who is responsible here?

As Pablos reply you should request this from the reseller. From the reseller site
