Bad Exsperience

So I app**** for a Huyndai Santa Fe exec. Me and my Husband wanted to trade in our vehicles for the Hyundai. The application was proccesed . They came back to let me know it has been approved. Obviously we were already excited to get the vehicle. Next day I get a call they used a wrong code they financed a Hyundai Santa Fe Elite and if they fix it to the right vehicle we need to pay 50 000 deposit wich we dont have. We were so disappointed. After a while it was fixed without deposit. The afternoon I went to the garage to sign a contract to get the vehicle on Monday . I signed the contract everything were fine. Today ( Friday) They let me know the deal cant be processed. Having excuses I dont even get. I spent my current vehicles installment on black Friday because I signed and wil not be paying any installments this month. Now the contract was canceled because of a million excuses that doesnt even make sence.
