To make it formal, you can write a statement saying your dealer broke the promises, therefore you have no other ways but to cancel the purchase.  Make a copy for yourself, in case they pick on you and you can go to claim court to protect yourself.
They dare not to charge to your credit card if you have given them.  
what kind of personal information? they can't use it without yo
