Ordered a Gateway 3DS from this site on the 2nd of February. The order did not ship until a week later because they had a problem shipping to a P.O. Box. No big deal. I gave them a different address and the order was shipped the next day. I never received a tracking number which is something the shipping page on their site said I should get after the product is shipped. Three or four days later a package arrives from them, but there's no gateway inside. Instead I find a power cord which I did not order. I try to remedy the situation by e-mailing them four times within a span of 3 days stating that I received the wrong item and that I wish to be sent a gateway, which is an option listed on their site. Still no response. What should I do?
