I purchased via television, 2 sets of the Precision Induction Cooktop.  This purchase was to include 2 free extra cooktops, 4 - 9" PerfectGreen Frying Pans, & 4 - 10.5" PerfectGreen Frying Pans.  The frying pans weren't shipped and the invoice said they were on back order.  I have placed several phone calls and have emailed the company and never get a response.  I would like to send one of these units (consisting of 1 purchased and 1 free unit) back and cancel the skillet order on at least 2 sets of the frying pans.   Assume I need a return authorization number to do this and get my refund.  Hope you can help me.
