National Marketing Classifieds - Wont stop calling!

For several weeks we had been getting calls every couple of days for some outfit selling duct cleaning services. One day, I answered the call and listened to the automated voice message. At the very end of the call, it said "If you would like us not to call any more, please press 3." I did that and haven't been called since.

I had a hard time understanding why a company almost 100 miles away was fishing for business or why a home heated by electric baseboard heaters would need duct cleaning!.
