spare key was not given to me

I bought the car from Kent motors in 2010, I have proof of e-mails that was sent to Kent motors asking for my spare key since i bought the car. I made calls to them but still nothing happened. Now i need the spare key because other key is giving me problems , when I call today a guy by the name of Louis said i just need to buy a new car, and he is very rude, he thinks he is doing me a favor, and when i ask him about the other manager on the e-mail (Francois@kent [URL Removed] and paulc@kent [URL Removed] and Dalene who was the sales lady )he said all of them are no longer with kents motors, I want them to give me my spare key or fix he key that i have with me. today because i cant lock the car and its dangerous. He even put the fone down when I was talking to him.
