I paid the visit. Everything is OK. Then I was presented with a way to buy the wines and receive them in Brazil.
As I loved the wines, I bought 12 bottles. The promise was that it would arrive in six months. And so far I haven't received it. And I already paid. Of course.
The view was in May. I try to contact and they don't answer me.
I am very upset and I would like to know how to get my problem solved.
CAUTION.
