X10 Shipped wrong product and expect me to pay return shipping. Internet

I previously purchased an Nstinct remote from X10.  Works perfectly and it was a good value.  A friend liked it and I thought it would make a good gift.  I found one being sold on ebay for a lower price than on the company website.  The ebay listing said it would take a while for shipping as it was drop shipped from X10. I called x10 and asked if they would match the price and was told yes.  I placed the order and received confirmation.  In a few days I received a different model that was a return.  I called customer service and explained that there were two issues, I did not receive the correct model and it was a used item.  They said I purchased a used item and that was why I got the low price.  The sales rep never mentioned that it was used when I placed the order.  Customer service said they would issue and RMA and send the info in an email.  When I received the email it stated that I was responsible for return shipping.  I called again and said I shouldn't be paying for return shipping when they send the wrong model.  The rep said they would submit my request.  X10 has not responded to that request or a follow-up email.
