This guy is selling duct cleaning now. Michael Hudson was the name he left but was an obvious alias.

when I answer the phone, no one speaks and then hangs up. very annoyed

This person has called many, many, times talking about water being unsafe, sounding, very intimidating and insisting that they are calling another person with a different name than mine.

yess they called me too. pretty stupid/waste of time aksing about if you are engaged or not and so on.

I got calls from these bastards too... This is what I did... I tracked the company that supplies phone service to the company that supplies phone service to them, they are based out of Toronto, call them and complain and tell them that you want all calls to stop or you are reporting them to the Better Business Beareau and the Police!The number is ?1-866-779-IRIS (4747) - Toll Free

That number also comes back to (416) 800-0323 (through (905) 695-5537). I have decided that I'm going to take some time out of my everyday and call them offering my design services, every day, Monday to Friday. I suggest that that's the best way to pat them back. Let's all make it a mission!
