Lack of Feedback, False Promises!!!

I made an enquiry about the new Qashqai /X-Trail, and was connected to Nissan Parow. Met up with the Sales Exec and we discussed terms, and how much I wanted to pay and the specs of the vehicle, did some test driving, and I was happy! They evaluated my car for a trade in and they were happy that they would settle it and I need to fill in all forms and waited for finance confirmation, and I didn't hear from the Sales Exec for 2-3 days despite several emails and calls I made with no response or feedback. Today, I called him again as I am planning a trip down to the EC soon, and the guy said he would call me again and he did not! I sent him an email, and he only response around 3pm (today) stating that they would be willing to settle my car only if I took a manual, not the auto which I wanted! I am so livid now because I could have gone elsewhere if he had not wasted my time like this, and making me sign forms and give him my documents for no reason! I am utterly disgusted right now!
