problem with hi-etech ebay shipper.

I saw New 7” A13 Capacitive 1.2GHz Android 4.0 4GB Tablet Flash 11.0 WIFI 3G White on Ebay for 71.99 USD with postage of 6.99. I got email that the item has been shipped with a tracking number LN263484889US on March 11 2013. Up to now I have not received the item. They told me they will refund only 20USD to me. I have try the tracking number but it does not exist. I think this fraud.
I am lodging a complain at Internet Crime Unit and I am looking for their contact detail, ie name, adress and telephone number. .
Please help me to trace this fraudulent company in Ebay.

DO YOU HAVE THEIR CONTACT DETAILS? PLEASE HELP ME

I HAVE ORDERED ITEM FROM THEM SINCE 11 MARCH AND UP TO NOW I HAVE NOT RECEIVED IT, BUT THEY DONT WANT TO REFUND MY MONEY TO ME TOO

Hi-Etech -
I bought a camera from Hi-Etech by Ebay.
The camera broken after one month, to solve the problem they send me to the camera manufacturer.
The customer service is very bad and after one year I lost my money and I don’t have camera.
