Dialed several times and hung up after I answered.  Busy signal when I called the number.

they call but hang up when I answer. WTF?

same thing - they hung up when my wife answered.

I just received one of these calls. It did say Ultimate Chimney,but they didn't leave a message. Annoying!

I just answered this call, told the person I was on the DO NOT CALL list.  They told me they were sorry for the inconvience and I told them that it was illegal to call me and they hung up on me.  I then called them back and their manager assured me they don't call people on the DO NOT CALL list.  I told her that sounded impossible and it sure looks like they are LYING!  What good is a do not call list if they can call you and THEN remove you from their list.  Given these practices, I would NEVER use their servcies!
