Camelback Toyota

Everything was great, then we got to finance guy, Miguel, who was so shady. They offered me a 12% APR for the car which I declined because I got an approval from my credit union for around 7.5% APR. He said he will work with my credit union and I was allowed to take the car home. Weeks have passed with no updates, then all of a sudden I saw my credit being pulled again multiple times without my permission. I texted him and he said he will reach to my credit union. A few days later, I got an email with Capital One and my loan is with them with 12% APR!!!! He never updated me that my loan with go through Capital One with the same APR that I declined in the first place. I texted him about it and I said what happened to my credit union. He said he forgot to text me that it never went through with my credit union. I have an 800 credit score. I replied saying you got me the same APR that I originally did not want? He never responded and I went thru another credit union again with 7% APR. Never been treated like that from any other dealerships.
