Antelope Valley Chevrolet Finance scam lancaster California

This scam is unbievlable, I went to this dealership and test drove a Cruze to purchase. After the test drive I decided to purchase this car to drive on my vacation to Tenn. in late August. After dealing with the sales man and his sales manager we made a deal. The deal was 0 percent for 72 months and I wanted to put 4000.00 down and I did. This is where i got scammed by the finance manager Paul, he had me sign papers stating there was no extended warranty which infact he charged me 2600.00 for one. He also had me sign a due bill with nothing on it and then there was an alarm for 500.00 typed in one of the lines. There was never any talk about an extended warranty or alarm system, think about it I bought an Lt with a 100,000 mile warranty standard with on star with gps and kill safe pertection. Ok , so now we go to the contract this is where I should have picked up on the scam. He had me signing so fast that I didn't have time to read anything, then he folds the contract up and put it in an envelope and tapes it shut. That should have been a giant red flag , but the guy was so nice and slick like a snake. Please be carefull if you ever go to this dealership, read all papers before and after Paul has them in his hands . He scammed 3100.00 from me and my family, I hope someday he gets caught.
