Bid or buy

Still the matter is not resolved, no item received or refunded.I have purchased Order ********** 5, but have not received it, the seller had send it with speed courier service, but i have not received my item, it was send to Port elizabeth, but where I dont know. I have contacted the seller, but he just refer back to the courier service, why did I pay for a courier service if i dont receive my item? The online support only refer me to the courier service, but they guarantee you will receive you items or money will be refunded.
