Doggie update

Ok, so I found out that the doggie with blue eyes is a pitbull, not suitable for a person like me at her first dog experience.
So I browsed another site, saw the pic of a doggie I liked and wrote a presentation email to them asking if the doggie was still awailable for adoption.
No reply.
I called them this morning. The lady said she hadn't got any email, anyway that doggie had already requests, I told her that there was another doggie I could be interested in, and she replied to fill in the adoption form, which I did immediately. I also resent the email.
No answer.
I called again asking if there were problems and if I had to keep searching....and she replied: KEEP SEARCHING!!!!

Now, I'd like to know why........I'm quite mad at this.
You see all these heart tearing ads, you call because you wish to rescue a doggie from a dog shelter, you call and do all the stuff and they say keep searching.....ARE YOU KIDDING????

I am a good person and wish to have a dog, but it seems like I'm trying to adopt a baby.....this is a nonsense....how many poor dogs out there and not able to rescue one.......... :(
