Query: Seller discontinued the order and never even let me know!!!

The seller put these items up for sale, i bought them - received the order placement email but then never received anything further - a few weeks later I inquired because I hadn't received my batteries and i found out that the seller had cancelled the order because they had run out. and then never even bothered to inform me. Horrendous doing business with this seller.
