FactoryOutletStore.com Refused to reimburse me for cost of return postage Internet

I ordered a replacement for the automotive charging cord for my Garmin Nuvi 200. Factory Outlet shipped me a charging cord for a Blackberry. I tried to use it but it didn't work with my Garmin Nuvi 200. I called them and they advised me to return the Blackberry cord. They would send me the correct cord once they received the Blackberry cord. They said that they would credit me the shipping cost to return the Blackberry.

They sent me another cord, but it was the exact same type as I had just returned, a Blackberry.  I called them and they informed me that did not have the Garmin 200 in stock (and, I assume, were no longer carrying it)  and said they would refund the original purchase price of the Garmin 200 power cord.  I asked about the return shipping cost of the Blackberry cord. They told me that since they didn't have a sale to me on the original part they could not reimburse me for the cost of shipping the Blackberry cord back to them.

The decieved me by advertising on their website regarding availability of the part. They sent me the same wrong part twice. They lied to me about reimburising me for the shipping cost. They still advcertise on their website that that they have the charging cord for the Garmin Nuvi 200.
