I believe this is Hanson's windows...we got an in house quote from them 2 weeks ago and they have called several times a day every day since! They give you a ridiculous quote and when you decline they call and say that they have a new rebate and the price of the quote has gone down substantially!
The same thing happened to me, after I entered the Home Makeover Contest! Hansons is a scam, don't ever cause, use them, or give them your personal info/phone #. I had someone out to give me an estimate last year and the guy was a total tool, and treated us badly just because we wouldn't give in and accept his quote for siding.
Ever since I switched cell phones about two weeks ago, I've been getting these calls from the above phone number! I seem to get them every business day. I didn't get any over the weekend and on Friday because of the holiday, but as soon as Monday rolled around, they called again.
