Conn's Rebate not honored Shreveport LA

I purchased a furniture set at my Conn's and was to receive a $200 cash back upon completing the first payment.  When I attempted to claim the cash back offer, I was given the run around about the offer, including that I did not qualify.   At the time of purchase, the cash back offer was used as an enticement to close the deal and I was told that I would have the cash back in time for Christmas.  After months of futile calls to various entities Conn's referred me to, there was no resolution.
