ONLINE PURCHASES

I have made an online purchase at Detectionk.com in the USA. I have ordered a pair of shoes and was actually impressed with the service. But when I received the shoes, I ordered a size 5 and according to International standards it is a 38. I received a 35! They do not want to exchange(because of costs) and offered me USD 5 as compensation, which is ridiculous! I cannot do anything with the shoes, because it is actually a size 3. They claim it is made in the USA, but there is no brand name on the shoes. Their return policy states that a person is eligible for a return and refund.PLEASE BE ON THE LOOK OUT !!!
