Purchase cancellation

CrabslayerT · 2016-12-11T18:27:37.000Z

My mate has made a purchase and the seller stated their location as UK. He paid and estimated delivery date is 29th Dec. He tried contacting the seller but no response. Checking on tracking brings him to the Japanese eBay site and an error message. Can someone advise of action to take and how long he has to cancel the order?
