Brand avoid no support Desigual if manufacturing defect.

So I contacted the customer service Desigual wants me absolutely not trade it because I have not bought in a store Official Desigual.

According to them, this is the store where I bought it (Amazon.com) to take on poorly made seams by Desigual therefore a manufacturing defect.

I confess I have never been confronted with a society that is leaking as much its responsibility for manufacturing defects and is so close to an exchange.

I know that the goods were manufactured by them and I do not see how the responsibility of a dealer store is taken into account.
