Phillips Chevrolet showed me fake invoice,high pressure sales tactics,lied about car being on the way,could'nt back out of deal frankfort, Illinois

After stating that im not going to buy car unless its  at invoice price , i was shown an invoice with a price  circled .Was told that it was the invoice price.Giving my keys up for an appraisal,was my first mistake. Second mistake was saying i was going to go to RIZZA CHEVY,because i knew TONY RIZZA.I couldn't get my keys back,gave them my credit card so they could check my GM points,salesman that i handed it to said he didn.t have it ,i basically couldn't leave if i wanted to.After haggling on price,i made an offer of $30,000 all taxes fees,transfers everything,with that said the salesman left me standing there again for at least another half hour .Returning with MIKE MAHARES the sales manager ,who by the way was suppose to be a friend,said they found the car i wanted and they would do a dealer trade and have it there in an hour.He said they wanted 35,000 and my trades ,which by the way there weren't even giving me wholesale for.
Finally agreeing on 31500,out the door all taxes,fees, etc. he shook hands on it. Was  told car was on the way and had to wait for finance.After being here for 5 hours,i finally was given my charge card and brought into a small room to sign papers,thinking the high pressure sales tactics were over was my third mistake.after signing mileage statements and title transfers,on the bottom of pile was the sales contract. Looked at it and seen that the total price was 34,800.I said i wasn't signing it because that wasn't the agreed price.the finance guy looked up and gestured to someone standing behind the glass partition and with that here came MIKE MAHARES, JOE LUGUE, the salesman and MIKE PORTER, the used car  salesman,blocking the door to that little room. MIKE MAHARES stated that he never agreed to 31500 but it was in fact 31500 plus taxes, fees,etc,With that said Joe Lugue chime in that he was standing there and that they didn't agree to 31500,also MIKE MAHARES states that there was no way i could back out now because they already had the car on the way and no matter what it belonged to me.Feeling trapped, thinking i need to get out of here,chevy giving me 5000 cash back ,they lowered the price to 34,100 i caved in and signed.I WAS SURPRISED TO FIND OUT THAT THE CAR WAS STILL AT THE OTHER DEALERSHIP.It was still going to be another hour at least before it got there. Thinking it was over,i returned to dealership with titles to my trade ins and surprise i have to pay another $120 for a title transfer,or i can't leave.Think that its over surprise,i'm at RIZZA CHEVY 1 week later talking to the service consultant because my brand new car has a flat tire and we look up my cars price info and i see the true invoice on my car is $2000 lower then the price i was shown.So buyer beware don't shop at phillips chevy by yourself,don't give up your keys,don't take anyones word or handshake on anything, get it in writing first ,look up the invoice price on car quotes .com first.
