Huntington Beach Ford screwed me on my regestration huntington beach, California

Good afternoon ,
 My name is Robert Quinn.  I purchased a pre-owned 2008 Ford F-250 on October 03, 2010 after trading in my old truck from Huntington Beach Ford, Huntingtton beach, CA.  I was never told that the california regestration had expired on the Ford on Febuary 28 2010.  So when i got the new california tags in the mail they expire Febuary 28, 2011. I paid the full regestration of $748.00 on october 03, 2010 when i bought the truck and now i have to pay the regestration again in febuary, i'm in the military and its hard enough in california because the regestration is so expensive.  I don't believe its fair at all that i 'm responsible for the 8 months of back regestration BEFORE i owned the truck.

When i contacted the dealer i bascially was told, "oh well", i asked them to reimburse me from Febuary 2010 to october 2010 for the regestration amount when i did not own the truck, they were no help. I bascially wanted to know if there's anything you can help me out with because i was never told that the resgestration expired 8 months prior and that i would be responsible for that, so now in a month and a half i have to pay the regestration again for $712.00, thats really not fair when i just purchased the truck in october.  Oh i also contacted Ford Corporate and they told me that they cant do anything because each dealership in individually owned, please help. i dont want anyone else to get takien for a ride on this regestration issue.
thank you for your time,
