Hello,
Its really a painful for any buyer in case of non receipt of material after making payment. Sometimes it may happen due to shortage in stock, but in that case seller generally intimate the buyer.
Any way you are on the right track to get refund your money. For your information in such case it may need approx a month by eBay Purchase Protection team to refund your money. But surely you will get refund.
Regards
