Is this Fraud. Do I have a case?

I purchased a 2008 Chevy Impala in March 2009. I later found out that the car came with a 5 year/100,000 mile Transferable warranty. On my sales contract I was charged $2,000 for warranty. It does not say powertrain or Bumper to Bumper or extended warranty. I have never received a warranty information and when I call the dealership I always are told that someone will call me back. What can I do? I am being charged finance charge on a warranty that already exsited.
