Query: Item Not Received

I have purchased this product in January of this year and have not received it. I have asked the seller for information on its whereabouts and have had no response. Please let me know what to do. I'm not sure how I purchased this item but it could have been my American Express. What is the issue and what do I do next? Why would I need to contact the seller again. Can you help me with this?626-931-0055 or cell 626-484-5552Thank you, Lolly
