Hoy Fox Toyota changed price on me after i drove off lot El Paso Texas

Hoy Fox Toyota i drove off with a 2018 Camry. I was approved by credit union for the loan. I had purchase order for $27,000.00 out the door. The sales person told me that when i got to credit union let her know because she made an error and entered the incorrect vin #. She said the car i had was a little more $300 or so but they would eat it since it was her fault. When I called for the corrected purchase order, it was for a little over $31,000. I called her she said no problem let me fix it and resend it. She calls me back she is very sorry vin # she enter is incorrect again this car the one i already drove off lot is higher and they can not take sure a huge loss but I can have it for $28,500. I said no, even thou the bank said they would finance. It's bull s**t, I said no. She said they could not take such a huge loss but $28,000 and 5 years free oil change. By this time I dont trust a word they say I told her Im bringing the  car back end of story. She said she would have to inspect it since I drove it and kept it overnight. I said ok but dont think we are discussing it and renegotiate . What does she do, bring a manager to talk to me. He wants to apologize on behalf of Mr Hoy. I'm sure he does not even know this happened. They kept on talking I finally just walked away and they did not even inspect the car, they wanted another change for another bull sh* attempt.

I went to El Paso Honda, very professional and hidden bull sh*.  Went very smooth.  I love my new 2018 Accord.
