I ordered something in early October. A day later (Oct 7) came the notification email saying "your order has been shipped". Well the seller only gave me a tracking number, which is not fake (it's in China Post database) but there is no tracking information whatsoever aside from "electronic information received". The seller did not answer my polite questions, so I opened a dispute (also with a polite but straightforward message, wanting a full refund) but there has been no response. I don't know what to do anymore.
