I ordered a uniform from this company. When l got it l did not like,so l returned to them and they confirmed they have received the items. Up till now they have refused to refund my money back. All l received from the account department is payments invoices. I don't need invoices, l need my money pay back to my account.....l have emails them.more than 10X,since 11th of May ,try to explain to them that l have not received my refund.l have try to contact customer services but no reply. I very worried and l don't l not know if it is a scam. Fake
