Waist Gang preshop I've order $706.70 , thinking my order coming after they create a shipping label . Order purchase on March 2 -2015, called the post office and they said a label was created but they never received the product Internet

Purchased order March 2-2015, so they send a email saying tracking number and shipping label created, but called today which is now March 10, and the USPS said they never received the product, now guys I've spent $706.70, email respond that was not helpful; called all extension no answer mailbox full; no call back; no update. I was very excited thinking I'm getting my product but no so it really is a Rip off, it might be company but not the one online. So course I've called my bank to do a dispute
