Cleburne Motorsports Offered extended warranty, and ripped me off Cleburne TEXAS

I purchased my 05 dodge neon srt4 at Cleburne Motorsports in Cleburne Tx.i also had a trade in as well.Well we live in San Antonio Tx and its about 4 1/2 hour drive. When we get there everything was unorganzied the car was not ready as told,they had all there kids in their small office where we had to wait for Julie Clark "owner" to meet us their. finally we were signing the buyers guide i told her i also need the extended warranty like i had mentioned over the phone the day before i drove out their.She then said oh thats right and added it onto my buyers guide a total $1,350 for the warranty, at then she coiuld not get me an accurate warranty because of the car i purchased has turbo on it, she said that monday she would find a warranty around that price and fax me the warranty info. so i was left to belive that i would be getting my warranty faxed.Well monday came and i called and called and finally got a hold of her.She said she was not in the office,but when she got back she would fax it to me. well no fax thatday and so on. Then a eek went by, another week, and same excuses everytime i spoke with her. well a month went by and i get a notice in the mail and im late on my old car that i had traded in a month ago.I then call her agian to see what was the hold up, she said that they been real busy since they left on vacation. i also asked about my license plates,my warranty and she told me she had sent them off. which was a big lie. after calling her and arguing with her she sent the plates out finally 2 weeks later but still no warranty! ive called everyday and she has got more rude every time i call her til the point where she told me that its not her problem that i have not received my warranty info, and she hangs up or tells me that if i keep bothering her i wont get it. please any one that can help me resolve this feel free to leave a meesage! i am desperate at this time but dont know what i should do ? should i drive 4 1/2 hour drive and argue ? next buyer please be aware of this dealership and dont be fooled by them.
