eBay - buy 1 get 1 50% off adidas

Purchased an adidas all terrain on last April, was broken on the side one month and half later. Contacted adidas ebay, was told "sorry but nothing they can do since it has been longer than 30 days". Claimed warranty through Adidas, was told to send it back for inspection and a prepaid shipping label will be sent to me. Nothing reached until a month alter, called again. Shoes sent out, nothing happened since last October.
