Percision Induction Cooktop Nuwave Ripoff, cheats, unreliable Libertyville, Illinois

My mother purchased the Nuwave cooktop on June 23,2012.  It was the buy one get one for just the shipping cost deal.  She has had the full amount charged ( and has paid ) to her credit card; but she has only gotten one cooktop and one pan.  We have called this company, left messages, ( because no one is available to tale the call ), and they are simply ignoring this problem.  My mom is a senior citizen, living on a fixed income and this is not acceptable busness practice.  What else can be done?
