If paid by Paypal, log in in your Paypal Account, go to the resolution center and open a dispute for "item not as described". If the seller doesn't respond to you, you can escalate the dispute to a claim. Paypal will investigate et give you a refund. If no move by the seller or you after 20 days, the dispute automatically closes!
Be careful if the seller asks you "to wait a few more days" or to "wait, he will reship another item" or "cancel the dispute before and after he refunds you". Close the dispute ONLY AFTER refund ou AFTER genuine item received.
