unwanted contour

We were told that our old cable boxes would stop working soon, so we took the old boxes to the Cox store to exchange them for the new version of the same box. When the guy came back with contour boxes we said we didn't want it but he said it was free for a year and gave us no other choice but to take contour. Well I got it home and all set up, everything working and it took a very short time to see it was nowhere near as good as the old box. I just want to get the new version of the non-contour box, will that be possible?
