car purchase

I made an offer to purchase a jetta 5 at the above mentioned supplier and needed finance. My dealer was Maree volchenk. To my surprise I heard through insurance broker that my deal was approved and that crystal asked them to give options of which insurance company would I like go with. I was shocked because I didn't even know what my instalment was going to be. After a day of waiting for Mares or Crystal to call like they did when they needed payslips and bank statement, none of them did. I took it upon myself to find out from chrytal who told me that she thought mares got hold of me. An hour later I received an email from crystal informing me that the car has been sold to a cash customer. I never received an apology and no explanation was given. I'm just wondering what if I gave the insurance company go ahead? How much paper work was I gonna have to fill to cancel It? And I just need to understand if they take individuals credit rating seriously.
