Hello,
My name is Larissa, I´m from Brazil. I purchse de Emotiv EPOC 14 channel but the Brazilian customer is holding. They want me to pay U$ 2.000 because the value of the invoice is diferente from the product value. I receive a copy from the invoice and the value there is U$ 151,15. I want to understand why there is this value in the invoice and not the value of almost U$ 1.000 that I actualy paid.
