Multiple calls with no voicemail

Many calls - no messages. I finally decided to call them back and was told they were 'WindowPrice.com'. I foolishly filled out an online form in hopes of finding out what kind of tax incentives or rebates I might qualify for if I upgraded the windows on our home. I have been inundated with marketing calls ever since. After these guys identified themselves, I went to the url www.WindowPrice.com and they have no webpage there,
