Radio/tape Cd Player problems of the 2010 Dodge Caravan

There is a known recall now for 2008-2010 Dodge Caravans for the ignition switch or win module malfunctioning. My van started with not turning completely off when the key was in off mode and removed from the ignition. The radio would still be on and lights on the dash with the key completely out of ignition. I had to remove the battery cable to get the van to turn off completely. This worked for a couple days but now it will not start or run at all. The error on the dash display says "bad key" and I am unable to start or use my van at all. When asked about recall they say my van doesn't fall into the months they issued the recall for in 2010? I am going to have to get this fixed because I cannot use the van otherwise and to replace the win module it is going to cost me around $600 (which I do not have!). I just purchased the van on memorial day weekend 05/2015 so I have only had this vehicle roughly 3 months and it is already broken down. Not a happy customer!.
