Contractors not getting back with me.

I called a local guy about installing laminate countertop in the kitchen. He came and took measurements and said he would get back with me. I waited about 4 weeks, called him back, and he said he would drop off estimates on Wednesday, that was about 5 Wednesdays ago and I have not heard from him. I called and left 2 messages over a 2 week period, asking if he was still interested in giving me estimates......I never heard back from him. Ugg, Why do people do this? If you are too busy, don't want the small job, just say so and I will move one to someone else. This guy, when he came, was very nice, we talked about what I wanted, he appeared to be interested, but did not get back after he was here. I have given up on him and moving on to get an estimate from someone else. So frustrating.
I know he does good work and is busy.....just a small guy in the business.
