Epic auto sales Lied and up charged Cypress Texas

 This car was listed online as $27,900 dollars and was told I was getting it for $26,000, after the paperwork was completed and I spoke with the bank that finance to me they told me they submitted it as $32,000. As the paperwork already completed as I was rushed to get out of there and dropping $6,000 down. I am now stuck with an additional $5,000 or so that I have to pay because I was rushed out of there. Also I told them I did not want an extended warranty and they told me I had no choice at $3000 and my AC already having issues which is not covered under this phenomenal extended warranty that they offer which now I am having taken off of my account. When I spoke with the manager or whatever he said he was he said that he would try to talk to the owner to fix my AC after I explained all of this to him obviously with me signing the paperwork I'm not going to get any money back on the financed amount. Also no response from the sales guy who told me the car would be $26,000. Very displeased for waste of time and money
