Action Pro White False and misleading advertising Las Vegas, Nevada

I viewed an ad for Action ProWhite on pch.com. The ad indiacated a Free trial of teeth whitener for payment of shipping only of $1.80.  I felt this was a good deal and ordered. Upon reviewing the statement after entering my credit card info, I was charged over $4 for the shipping. First misleading event. I e mailed them immediately requesting they cancel my order as they had falsely advertised. My card had been charged immediately and they sent me an email indicating that my account had been canceled. When I received what was supposed to only be the trial, it included a full order with two Pro White pens. When I e mailed them AGAIN, I was told that if I did not send the two pens back by 2-28, I would be charged 90.14. THERE WAS NO INDICATION ANYWHERE THROUGHOUT THE TRANSACTION THAT STATED I WOULD RECEIVE AN ENTIRE ORDER AND HAVE TO PAY FOR IT. THE WHOLE INITIAL AD MISLEAD ME. I have mailed back the items, which I had to pay for the return mailing and I e mailed and called them also stating that I best not be charged for the 90.44 as the item that I DID NOT EVEN ORDER had been returned. I really feel abused when dealing with companies that mislead and false advertise their products.
