Dears, good morning! I inform you that the site clikouchegou.com.br redirected with sales on shopify is false and is making sales using my Logo, business data, company name, and CNPJ, they need to be removed from the urgent air, as they have already added me on the complaint here and are selling without deliver products to customers who are having losses. Remove Urgent Air and find out who is committing this crime. Thank you Fábio R. Carvalho
