Dealer Vehicle Finance Support Bad Attitude

The lady in your dealer vehicle finance support needs to learn how to speak to people and how to answer a phone. I called today querying the interest rate the dealer gave me for my car not knowing this is confidential. This lady acted as if I was asking her for FBI secrets instead of politely telling me it's confidential. I didn't really understand what she was saying in terms of shopping around as the deal application is valid for 30 days. Her attitude is really bad and I feel sorry for dealers who get that kind of service on a daily basis.
