Nuwave Precision Induction Cooktop RipOff Libertville, Illinois

I ordered my Nuwave Precision Induction Cooktop from an advertisement on television that offered a buy one, get one free for $99.99 + S&H. The $99.99 was to be divided in three equal payments to your card.
My $99.99 + S&H wound up costing a total of $301.64 and was not spread over the 3 months. The TV ad showed you would get 2 cooktops, and 2 sets of the stainless steel pans & 2 sets of the 2 frying pans + 2 the carrying case.  
I received only one cooktop and one set of the other items that was suppose to come free with my order.  The shipping & handling for the cooktop was $29.95 and for the other items another $69.95 but the entire set came in one box?  When I called about my free set I was told that I did not pay for the shipping of the other items that was suppose to come free in the buy one get one offer.  I explained that I had already paid $247.65 in shipping & handling charges and I was charged for the carrying case when it was suppose to come with the set. The person taking my order confirmed with me that I had paid the shipping & handling on both sets. 
 I was told that I did not pay the $69.95 shipping&handling for the free set. I would need to pay another $69.95 to ship my free one and in order to get the free carrying case I would have had to have spoken to the automated system and not a company rep.  The customer service rep did give me an 20% discount on the shipping&handling for my free set but I had to repeat to him several times that I did not get the free cooktop either. Bottom line the TV ad is false & it looks like they get away with it.
