I bought a Toyota Camry se metallic black 2017 on 05/21. The only person I would thank is the internet sale manager Anthony he was a great help

Before even starting I said i will buy the car only if I get if for 0 apr , the sale guy agreed and We had a discussion finally came to conclusion and finalized with terms for 0 apr (credit score 651) for Camry se metallic black we will get it for you and asked me to deposit $500 , which I did , he also said the maintenance plan is for $1760 and its optional

Next day The sales guy said the car loan is approved 0 % apr and car is on its way , waited and after few hours it came and then I was expecting it to be a button start then I said fine if it's a key start ,

Mean while I paid for the insurance of the car as a condition (nation wide )

Then I was waiting for the finance and signing the paper work, here come the major twist
I said I would not want to take the maintenance plan for $1760, he tried pushing I said no ,
Then he started , you have a credit score of 651 , you just have job , recent graduate nothing more than that . I don't understand who said you qualify for this , your loan will not be approved if you don't take the maintenance plan , now was lil rude and he took 1 hour made me feel awkward , then I said ok please include that maintenance plan then he said now it will be approved . This is not done. For a week I kept on asking the sals guy for the update on approval

I paid the down and he let me take the car

Until today I feel bad about that

Plus the insurance agent helped me find a policy (nation wide ) and he made the collision deductible to $5000 with out informing me and now when I trying to cancel the policy nation wide people are transferring to the agent but no response
