NutraSlim5 Fat burner, Product Preview Phoenix Arizona

A female representative called me on November 18 and told me about this NutraSlim5. She identified 5 ingredients that correspond to the ingredients in NutraSlim HCA--I checked after the fact. She said I would be part of a study, that I could buy 2 bottles and get 1 free for $109 plus change, and for an additional $5 I could get express mailed and get it by Tuesday 11/22. I asked the representative for an email confirmation of my order and she agreed. I never got said confirmation. I complained about it using the online form to say I didn't get a confirmation email. No one ever responded to those two forms. I finally got someone on the line at on the 21st and they said it was just mailed out. Then I got email saying they mailed it and included a tracking number. I checked that tracking number with the Post Office several times after a day and got a notice each time that they didn't recognize that number. Sure enough it was not in the mail on the 22nd. I received the bottles Saturday--December 10! This is after I contacted the Postal Service and made a complaint about the company and they initiated an investigation and after I filed a complaint with my bank to stop the payment. Today, Dec. 12, I called to get an RMA number to return the product and the man answering the phone said I couldn't return the product!!! He said I hadn't tried it and that I could only return a product if it was the wrong product. I never heard of such a thing and the woman who called and took my order never mentioned anything like this. I think this is a scam and the now I think the product's worthless. Has anybody else been contacted about this product?
