Hi,
If you paid with your credit card, call your cards provider and tell them that you never recieved the goods and you wish to have the item "charged back" to your account as you never recieved them, use the term "charge back" as this is the banks term for refunding your money.
Your bank will send you the forms to fill in, once they have recieved them your money will be credited back into your account, but beware the seller may submit your payment details again so you may need to go through the process again.
This is what happened to me, the only difference was that I paid via Paypal, but in the end I got my $$$ back.
Goodluck
Tony
