You should contact your credit card provider -- file a charge back for undelivered merchandise.  
I ordered a Dell Inspiron 15 and a mouse in early September to be sent to Bronx, New York. The mouse was delivered while the laptop was sent to Lebanon, TN. I've tried to call contact support multiple times with no success. Every time I call them, they tell me the order was not completed due to a validation issue, that's why they sent the laptop back to Lebanon where Dell's warehouse is located. They also tell me a refund would be placed and I'd get my money back within 5 days. It's been almost 2 months and I haven't received neither my money back nor the laptop. I don't know what else I can do. I would like to, at least, know if Dell is going to make the refund or not.  
Dell refuses to give me a refund after not delivering my laptop
